Proposed patches
Tony Cook provides a new patch to fix tests in FreeBSD jail, [36]Perl
#127533.
Dagfinn Ilmari Mannsåker provided a [37]patch which normalizes the types
for lengths and sizes. It includes a good investigation and
explanation of
the situation. What Ilmari is asking is, should this be added while
approaching the full code freeze?
Tony Cook provides another patch for [38]Perl #122287 to handle undefined
symbols on illumos.
Sullivan Beck [39]provided a patch to update [40]Locale::Codes from
version 3.37 to 3.38.
Dave Mitchell provided a patch for [41]Devel::NYTProf to handle issues
relating to the new context stack system rewrite.
Discussion
Dave Mitchell provided [42]comments on [43]Perl #127638, explaining the
problem as a bug in [44]XML::XPath::Node::Element and/or [45]Net::Yadis.
It is an interesting read.
Chad Granum [46]bumped a thread on reviewing [47]Test::Builder using
Test2.
Maxwell Carey [48]asks about how Perl decided the package name in a
construct with indirect object syntax. Father Chrysostomos jumps to the
rescue with an [49]explanation.
David E. Wheeler raises a problem he encountered with the [50]encoding IO
layer. There are several explanations and additional information provided
on the thread by Zefram, Aaron Crane, and Leon Timmermans.
Linda Walsh [51]provided an idea for a feature, which turned into an
interesting discussion about a qw-like keyword that could interpolate
variables and maintain the spaces available in the original values. Lukas
Mai recommended [52]Quote::Code.
Håkon Hægland [53]asks for an option in core to make __FILE__ use an
absolute path. Zefram tries to find out what it is for and maintains
there's a better way to achieve the desired result.
