This week on the Perl 6 mailing lists
Remember, the next Parrot bug day is 13 January, 2007. Join the rest
of the team at #parrot (irc.perl.org) to work on closing as many bugs
as possible before the next Parrot release.

Numeric Semantics <http://xrl.us/t3o7>
Earlier, Luke Palmer asked for a clear definition of when math should
use floating points and when it should be integer-based. In response,
Darren Duncan highlighted a recent #perl6 discussion
<http://xrl.us/t3o8> on the topic. He proposed distinct operators to
allow users to explicitly choose the math mode. Jonathan Lang
mentioned that in the one other instance where there were
type-specific versions of a common operator, a third 'generic' version
was required. Dr. Ruud suggested giving numerics multiple faces.
More recently, Larry Wall responded to the thread, adding his thoughts
and musing on whether standard Perl should include convenience
operators like `idiv` or if there should simply be pragmatic support
for them. A great deal of discussion followed.

I/O PDD - ready for implementation <http://xrl.us/t77w>
After moving the I/O PDD out of the clip directory (see
'[svn:parrot-pdd] r16391 - trunk/docs/pdds/clip
<http://xrl.us/t77v>'), Allison Randal announced that implementation
can begin on the details in the document. She also welcomed comments.
Jonathan Worthington replied that he liked what he had read, but felt
that more information was needed on how role composition should work.
Allison replied that she was still at work on defining roles in the
objects PDD. She offered a short explanation of how it would probably
work.
Some discussion on how to implement error values also took place, with
Jonathan, Allison and Larry Wall contributing.

In ticket [perl #41168] <http://xrl.us/t77y>, Will Coleda added a

Re: [perl #41020] [PATCH] pmc2c.pl functionality extracted into separate
package <http://xrl.us/t3o9>

He provided a new patch in the hopes that it would solve the problem.
[NEW]: README for t/tools/pmc2cutils/ <http://xrl.us/t773>
James Keenan submitted a README file for `t/tools/pmc2utils`, which
was applied as r16409.
[perl #41173] [PATCH] Intel C++ is not really gcc <http://xrl.us/t774>
Steve Peters created ticket [perl #41173] <http://xrl.us/t775> to
report a problem caused by the Intel C++ compiler defining `__GNUC__`
although it is not compatible with gcc. He provided a patch which
attempts to address the issue. It was applied in r16412.

supplied a patch to correct the issue, which was applied as r16416.
[perl #41182] [PATCH] Preliminary support for suncc on Linux
<http://xrl.us/t78c>

suncc on Linux. This was submitted as ticket [perl #41182]
<http://xrl.us/t78d>. It was committed as r16417.
[perl #41185] [BUG]: examples/shootout/regexdna.pir.input: Persistently
failing test <http://xrl.us/t78e>

problem with a failing test in `shootout.t` on Mac OSX.
[perl #41186] [BUG]: tools/build/ops2pm.pl: Variable used in both
package scope and loop iteration <http://xrl.us/t78g>
Ticket [perl #41186] <http://xrl.us/t78h> was created by James Keenan
to report a possible bug in `ops2pm.pl`. He wondered if it was
intentional that a variable was used in two different scopes. His

<http://xrl.us/t78i>
Lee Duhem reported that r16418 broke a test. He supplied a patch, but

gather { if $xy.was_taken { ... } } <http://xrl.us/t3pt>
Earlier, Gilbert R. R??hrbein asked if there is a way to look inside a
gather-block if something was already taken. He included some example
code of how he thought it would work.
Gabriele Renzi replied with a code correction, but noted that it would
not work on Pugs 6.2.13.
99 problems in Perl6: problem 28 <http://xrl.us/t78k>
Gabriele Renzi decided to look at problem #28 from Ovid's list of 99
problems in Perl 6. Gabriele included a solution, but wondered if
there was a better way to solve the exercise. Ovid suggested checking
in the code, if it passed tests. Gaal Yahas provided the commit bit.
99 problems in Perl6: 32 and a question on number coercion
<http://xrl.us/t78m>
Gabriele Renzi provided an answer to problem number #32 from the list
of 99 problems in Perl 6 and added it to the repository. Gabriele
wondered what the expected behavior was for `gcd`. Steffen Schwigon
had some questions on the code, which Gabriele answered. Steffen
Schwigon
perl6-ish idiom for code and tests in one file <http://xrl.us/t78n>
Gabriele Renzi inquired what the Perl 6 idiom would be for keeping
code and tests in the same file. Juerd liked the idea of a macro or a
standard subroutine, as did Gaal Yahas. Larry Wall offered an
alternative using `MAIN`, but noted that autocalls to MAIN are not yet
implemented. He suggested a temporary workaround.
Compiler
[PATCH] fix wrong $include_path (of parrot) in Makefile.PL
<http://xrl.us/t78o>
