Sequence (?#...) not recognized in regex
Karl Williamson reports on a problem in Perl's regex engine which he's made a patch for. This thread goes over the specifics and asks RJBS how the patch ought to be applied to blead for 5.18.
How on earth did we manage to break pack() so badly
Yves Orton writes, um, a strong critique of the behavior of pack() since 5.10. He feels it's annoying and wrong. Dave Mitchell thinks it might need some tweaks but is basically proper behavior.
DAVEM TPF Grant April 2013 Report
Dave Mitchell gives his monthly summary of work done on perl as part of his TPF grant. These are always interesting reads if you like to track the history of perl bug detection and squashing.
Problems with Carp::longmess() in 5.17.10 and before
Watch live code archealogy as P5P digs deep into some messy internals of Carp.
What does PERL_HASH_SEED do?
Steve Hay asks about the variance between the documented behavior of this environment variable and the observed behavior in blead.
