Patches, crashes, hashes and stash caches, these are a few of my favorite things. If you like them, too, this week's P5P summary is for you !
Arthur Bergman has the idea to use a cache to store symbol tables (a.k.a. stashes) for class method calls, to avoid looking them up from the package name each time they're invoked. He proposes a patch, with which he observes an average 180% speed increase (on his system).

Ilya Zakharevich submitted a load of patches to maintperl, some of them related to the Perl port to OS/2, some of them more generic, to MakeMaker, Net::Ping, Time::HiRes. He also posted some comments about the ithread implementation in 5.8.0, and tried to have microperl working. (Look in the perldelta manpage for perl 5.8.0 if you haven't heard about microperl before.)

And that's not all. He also proposed to add built-in support for the
now-standard --help and --version switches to Getopt::Std. This is
followed by a discussion with Johan Vromans about extending this feature
to Getopt::Long.

Alberto Accomazzi reports that perl 5.8.0, compiled with the
usemymalloc configuration option, doesn't seem to be able to handle
more than 1GB of RAM. This being most probably due to an inner limitation
(although nobody commented on this).

Bug #21765 is about split() not returning the desired kind of false/empty
value, when called in a specific assignment context. Yitzchak
Scott-Thoennes sent a fix. Demonstration here

Bug #21787 reports a problem with the fields pragma. Michael Schwern
says that this looks like a bug which was just reported in Class:Fields,
which includes its own version of fields.pm.
Michael Schwern, busy on the MakeMaker front, asked how portable the
redirection construct 2&>1 was, when used from inside the qx//
operator. Apparently it's portable on platforms that provide a shell that
understands it, on OS/2 (that provides an emulation), and on VMS, but only
when the external command run by qx// is perl.
Steve Hay provided several fixes to the installhtml utility, that generates the perl standard documentation in HTML format, and that was severely messed up.
Chip Salzenberg wonders, lonely, about the FIXME comments that can be found here and there in the sources.
Sadahiro Tomoyuki released new versions of Unicode::Normalize and Unicode::Collate.
