-always a typographical error.  Note that the earlier variable will still exist
-until the end of the scope or until all closure referents to it are

-
-=item "my sub" not yet implemented
-
-(F) Lexically scoped subroutines are not yet implemented.  Don't try that
-yet.
-
-=item "my" variable %s can't be in a package
-
-(F) Lexically scoped variables aren't in a package, so it doesn't make sense
-to try to declare one with a package qualifier on the front.  Use local()
-if you want to localize a package variable.
-
-=item "no" not allowed in expression
-
-(F) The "no" keyword is recognized and executed at compile time, and returns
-no useful value.  See L<perlmod>.
-
-=item "our" variable %s redeclared
+=item accept() on closed socket %s
 
-(W misc) You seem to have already declared the same global once before in the
-current lexical scope.
+(W closed) You tried to do an accept on a closed socket.  Did you forget to
+check the return value of your socket() call?  See L<perlfunc/accept>.

-(F) The "use" keyword is recognized and executed at compile time, and returns
-no useful value.  See L<perlmod>.
+(X) You can't allocate more than 64K on an MS-DOS machine.
 
 =item '!' allowed only after types %s
 
 (F) The '!' is allowed in pack() and unpack() only after certain types.
 See L<perlfunc/pack>.
 
-=item / cannot take a count
-
-(F) You had an unpack template indicating a counted-length string,
-but you have also specified an explicit size for the string.
-See L<perlfunc/pack>.
-
-=item / must be followed by a, A or Z
-
-(F) You had an unpack template indicating a counted-length string,
-which must be followed by one of the letters a, A or Z
-to indicate what sort of string is to be unpacked.
-See L<perlfunc/pack>.
+=item Ambiguous call resolved as CORE::%s(), qualify as such or use &
 
-=item / must be followed by a*, A* or Z*
+(W ambiguous) A subroutine you have declared has the same name as a Perl
+keyword, and you have used the name without qualification for calling one or
+the other.  Perl decided to call the builtin because the subroutine is not
+imported.
 
-(F) You had a pack template indicating a counted-length string,
-Currently the only things that can have their length counted are a*, A* or Z*.
-See L<perlfunc/pack>.
+To force interpretation as a subroutine call, either put an ampersand
+before the subroutine name, or qualify the name with its package.
+Alternatively, you can import the subroutine (or pretend that it's
+imported with the C<use subs> pragma).
 
-=item / must follow a numeric type
+To silently interpret it as the Perl operator, use the C<CORE::> prefix
+on the operator (e.g. C<CORE::log($x)>) or by declaring the subroutine
+to be an object method (see L<perlsub/"Subroutine Attributes">
+or L<attributes>).
 
-(F) You had an unpack template that contained a '#',
-but this did not follow some numeric unpack specification.
-See L<perlfunc/pack>.
+=item Ambiguous use of %s resolved as %s
 
-=item % may only be used in unpack
+(W ambiguous)(S) You said something that may not be interpreted the way
+you thought.  Normally it's pretty easy to disambiguate it by supplying
+a missing quote, operator, parenthesis pair or declaration.
 
-(F) You can't pack a string by supplying a checksum, because the
-checksumming process loses information, and you can't go the other
-way.  See L<perlfunc/unpack>.
+=item '|' and '<' may not both be specified on command line
 
-=item /%s/: Unrecognized escape \\%c passed through
+(F) An error peculiar to VMS.  Perl does its own command line redirection, and
+found that STDIN was a pipe, and that you also tried to redirect STDIN using
+'<'.  Only one STDIN stream to a customer, please.
 
-(W regexp) You used a backslash-character combination which is not recognized
-by Perl.  This combination appears in an interpolated variable or a 
-C<'>-delimited regular expression.  The character was understood literally.
+=item '|' and '>' may not both be specified on command line
 
-=item /%s/: Unrecognized escape \\%c in character class passed through
+(F) An error peculiar to VMS.  Perl does its own command line redirection, and
+thinks you tried to redirect stdout both to a file and into a pipe to another
+command.  You need to choose one or the other, though nothing's stopping you
+from piping into a program or Perl script which 'splits' output into two
+streams, such as

+    }
+    close OUT;
 
-=item /%s/ should probably be written as "%s"
+=item Applying %s to %s will act on scalar(%s)
 
-(W syntax) You have used a pattern where Perl expected to find a string,
-as in the first argument to C<join>.  Perl will treat the true
-or false result of matching the pattern against $_ as the string,
-which is probably not what you had in mind.
+(W misc) The pattern match (//), substitution (s///), and transliteration
+(tr///) operators work on scalar values.  If you apply one of them to an array
+or a hash, it will convert the array or hash to a scalar value -- the length
+of an array, or the population info of a hash -- and then work on that scalar
+value.  This is probably not what you meant to do.  See L<perlfunc/grep> and
+L<perlfunc/map> for alternatives.
 
-=item %s (...) interpreted as function
+=item Args must match #! line
 
-(W syntax) You've run afoul of the rule that says that any list operator followed
-by parentheses turns into a function, with all the list operators arguments
-found inside the parentheses.  See L<perlop/Terms and List Operators (Leftward)>.
+(F) The setuid emulator requires that the arguments Perl was invoked
+with match the arguments specified on the #! line.  Since some systems
+impose a one-argument limit on the #! line, try combining switches;
+for example, turn C<-w -U> into C<-wU>.
 
-=item %s() called too early to check prototype
+=item Arg too short for msgsnd
 
-(W prototype) You've called a function that has a prototype before the parser saw a
-definition or declaration for it, and Perl could not check that the call
-conforms to the prototype.  You need to either add an early prototype
-declaration for the subroutine in question, or move the subroutine
-definition ahead of the call to get proper prototype checking.  Alternatively,
-if you are certain that you're calling the function correctly, you may put
-an ampersand before the name to avoid the warning.  See L<perlsub>.
+(F) msgsnd() requires a string at least as long as sizeof(long).

-
-(W ambiguous) A subroutine you have declared has the same name as a Perl keyword,

-not imported.
-
-To force interpretation as a subroutine call, either put an ampersand
-before the subroutine name, or qualify the name with its package.
-Alternatively, you can import the subroutine (or pretend that it's
-imported with the C<use subs> pragma).
-
-To silently interpret it as the Perl operator, use the C<CORE::> prefix
-on the operator (e.g. C<CORE::log($x)>) or by declaring the subroutine
