|
|
one parameter expression, and puts it in scalar context, thus ensuring that it

doesn't corrupt the stack at runtime.

The list above is almost certainly incomplete as it is automatically generated
|
|
from version control history. In particular, it does not include the names of
|
|
the (very much appreciated) contributors who reported issues to the Perl bug
|
|
tracker.
|
|
|
|
Many of the changes included in this version originated in the CPAN modules
|
|
included in Perl's core. We're grateful to the entire CPAN community for

=head1 Reporting Bugs
|
|
|
|
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
|
|
L<https://rt.perl.org/> . There may also be information at
|
|
L<http://www.perl.org/> , the Perl Home Page.
|
|
|
|
If you believe you have an unreported bug, please run the L<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.
|
|
|
|
If the bug you are reporting has security implications which make it
|
|
inappropriate to send to a publicly archived mailing list, then see
|
|
L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
|
|
for details of how to report the issue.
