+=item In string, @%s now must be written as \@%s

+(F) It used to be that Perl would try to guess whether you wanted an
+array interpolated or a literal @.  It did this when the string was
+first used at runtime.  Now strings are parsed at compile time, and
+ambiguous instances of @ must be disambiguated, either by prepending a
+backslash to indicate a literal, or by declaring (or using) the array
+within the program before the string (lexically).  (I<Someday it will
+simply assume that an unbackslashed @ interpolates an array.>)
