In two words, this was a busy week. Various topics were discussed, from the low-level C portability stuff to the Perl language considerations.
*DB*File::delete Paul Marquess brings to the general attention that the implementation of
delete() in the DBM modules does not what the man page says what it
should do. This implementation glitch was due to efficiency reasons. He
wonders what's the right solution for this -- interface change or doc
change.

Stas Bekman notices that some form of concatenation of strings was impressively slowed down after the release of perl 5.8.2. This change is due to the removal of an aggressive optimization that went wrong on some cases. No replacement for this optimization has been worked out yet.

Tels reports (bug #24622) that you can't use Benchmark when you've
loaded bigint. Hugo van der Sanden remarks that bigint interferes
with Benchmark's use of floating point numbers. Tels then proposes
a patch to Benchmark to cope with this, but Hugo believes that a more
correct solution would be to fix bigint so its effect is lexical and no
more global. (And we're back to this old TODO item : fix lexical pragmas.)

Tassilo von Parseval remarks that perl lets you tie stashes (symbol table hashes). However, once tied, they don't work quite as expected. So it's maybe a good idea to forbid tying stashes (unless we can make them work correctly, for some acceptable value of correctly.)
On the other hand, one can mark stashes as read only, and this seems to behave.

Gisle Aas reports that the following code
if ("") { do_something() }
produces a warning, Useless use of a constant in void context. Rafael comments and thinks that this one will be difficult to fix. (Bug #24646).

Tels posted a abstract of the current state of Math::BigInt and
Math::BigFloat (and pre-released Math::BigInt 1.68).

Steve Hay proposed to add a function Win32::IsAdminUser(). Michael
Schwern proposes to put it in libwin32 instead. No Windows guru
comments.

Paul Marquess works on the DB_File and utf8 issue reported last week.
Enache Adrian works on old and new memory leaks. (E.g. bug #24624 for a memory leak related to the new version object code.)
Enache also fixed a bug related to mishandling of utf8 strings by substr().

Bug #24615 is, for once, about a case where perl's taint checks are too zealous.

Alan Burlison has problems building perl with a C99-compliant compiler.
This has something to do with #include guards and obscure predefined
compiler symbols, that are in the source code of perl from ages. Some
cleanup is in order.

Nicholas Clark, integrating changes to the perl 5.8 branch, remarks
that the recent fixes made to the $0 variable break PAR.

Nicholas also released a snapshot of perl 5.8.x at the very end of the week.
This is the ``camel grooming club'' - we have to make the hair as unhairy as possible while making things work. -- Nick Ing-Simmons, speaking about P5P.
