3 | perldelta - what is new for perl v5.9.3 |
4 | |
5 | =head1 DESCRIPTION |
6 | |
7 | This document describes differences between the 5.9.2 and the 5.9.3 |
d7f8936a |
8 | development releases. See L<perl590delta>, L<perl591delta> and |
496c75d0 |
9 | L<perl592delta> for the differences between 5.8.0 and 5.9.2. |

13 | =head2 Parsing of C<-f _> |
14 | |
15 | C<_> is now forced to be a bareword after a filetest operator. This solves |
16 | a number of misparsing issues when a global C<_> subroutine is defined. |
17 | |
18 | =head2 C<defined %foo::bar::> |
19 | |
20 | This used to report whether the C<foo::bar> package was created. Now it's |
21 | always true, as a side-effect of a change to shrink the internal size of |
22 | hash structures. Note that using C<defined> on hashes was deprecated |
23 | anyway. To achieve the same result, you can use the following |
24 | backwards-compatible idiom: |
25 | |
26 | defined *foo::{HASH}->{'bar::'} |

51 | |
52 | If you find what you think is a bug, you might check the articles |
53 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
54 | bug database at http://bugs.perl.org/ . There may also be |
55 | information at http://www.perl.org/ , the Perl Home Page. |
56 | |
57 | If you believe you have an unreported bug, please run the B<perlbug> |
58 | program included with your release. Be sure to trim your bug down |
59 | to a tiny but sufficient test case. Your bug report, along with the |
60 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
61 | analysed by the Perl porting team. |
