=head1 NAME
perldelta - what is new for perl v5.9.3
=head1 DESCRIPTION
This document describes differences between the 5.9.2 and the 5.9.3
development releases. See L<perl590delta>, L<perl591delta> and
L<perl592delta> for the differences between 5.8.0 and 5.9.2.
=head1 Incompatible Changes
=head2 Parsing of C<-f _>
C<_> is now forced to be a bareword after a filetest operator. This solves
a number of misparsing issues when a global C<_> subroutine is defined.
=head2 C<defined %foo::bar::>
This used to report whether the C<foo::bar> package was created. Now it's
always true, as a side-effect of a change to shrink the internal size of
hash structures. Note that using C<defined> on hashes was deprecated
anyway. To achieve the same result, you can use the following
backwards-compatible idiom:
defined *foo::{HASH}->{'bar::'}

If you find what you think is a bug, you might check the articles
recently posted to the comp.lang.perl.misc newsgroup and the perl
bug database at http://bugs.perl.org/ . There may also be
information at http://www.perl.org/ , the Perl Home Page.
If you believe you have an unreported bug, please run the B<perlbug>
program included with your release. Be sure to trim your bug down
to a tiny but sufficient test case. Your bug report, along with the
output of C<perl -V>, will be sent off to perlbug@perl.org to be
analysed by the Perl porting team.
