Perl 6 Summary for 2005-09-12 through 2005-09-19
All~
Welcome to another Perl 6 Summary, this time brought to you with a
shorter pause (::grumble:: $WORK ::grumble::) and assisted by cookies.
Perl 6 Compilers
Circular Preludes for Fun and Confusion
Yuval Kogman posted a really interesting idea of using a circular
prelude to facilitate creation of a new run time. If the prelude defines
everything it can in terms of itself (even circularly if need be), then
a new run time implementer can break the circle wherever is most
convenient for the run time. It looks really cool to me.

PxPerl Site Change
Grégoire Péan announced that he was having problems with his old domain
and that PxPerl is now hosted at http://pxperl.com
<http://xrl.us/hn6i>
Parrot
13! == BIG!
James Ghofulpo noticed that the example factorial program included with
Parrot gives incorrect results on 32 bit machines. Will Coleda offered
to clean the old PASM examples into shiny new PIR.
<http://xrl.us/hn6j>
Properly Formatted POD
Unlike these summaries, Parrot's docs should be in properly formatted
POD. Joshua Hoblitt provided patches to fix them up and test them.
Bernhard Schmalhofer applied the patches.
<http://xrl.us/hn6k>
Bad IMCC Error Message
Joshua Hoblitt opened an RT ticket for the error message imcc outputs
upon seeing a non-existent PMC. No takers yet.
<http://xrl.us/hn6m>
Globbing Like Tcl
Amos Robinson opened am RT ticket requesting Tcl Syntax Globbing in PGE.
<http://xrl.us/hn6n>
AMD64 Build Error
Joshua Hoblitt posted a build error involving posix_memalign on AMD64.
Warnock applies.
<http://xrl.us/hn6o>
TODO: Call for B0rked
chromatic the capless put out a call for specific TODO items that Parrot
needed. Many people provided suggestions.
<http://xrl.us/hn6p>
Documentation Keyword Tagging
Joshua Hoblitt opened a ticket requesting keyword tagging (via " ") .
<http://xrl.us/hn6q>
leo-ctx5 on Win32
François Perrad solved a few link problems on Win32 for the leo-ctx5
branch. Jonathan Worthington applied it.
<http://xrl.us/hn6r>
Support Different Compilers
Andy Dougherty provided a patch making it easier to compile parrot with
a different options then Perl 5. Bernhard Schmalhofer tentatively
applied it, but despite his fears nobody hollered.
<http://xrl.us/hn6s>
Tcl Leo's Context
My that sounds dirty.... Regardless Leo and Will Coleda, with much help
from assorted others) managed to get all of the Tcl tests passing in the
leo-ctx5 branch.
<http://xrl.us/hn6t>
4 Down 7204 to Go
Andy Dougherty posted a patch which eliminates 4 of Parrot 7208 compiler
warnings on SPARC. Warnock applies.
<http://xrl.us/hn6u>
Circular Finalization Returns From the Dead
Nicholas Clark wondered how Parrot would handle PMC loops with
finalizers. Leo and I provided some ideas. Nothing is officially specced
yet.
<http://xrl.us/hn6v>
"make clean"er
Joshua Hoblitt provided a patch which makes make clean cleaner. Warnock
applies.
<http://xrl.us/hn6w>
Pack Packfiles, Fix Fixups
Jonathan Worthington split the fixup and unpack functionality of
Packfiles so that he could later create a pbc_merge. Later he did that.
<http://xrl.us/hn6x> -- earlier
<http://xrl.us/hn6y> -- later
Taking Exception to Leo's Tcl
Some days my head is just in the gutter. Will Coleda update Tcl to use
exceptions for TCL_RETURN, which apparently simplifies things.
<http://xrl.us/hn6z>
Tcl on Windows
Jerry Gay noticed that Tcl was not building on Windows. Will Coleda
suspected that it got fixed; he was right.
<http://xrl.us/hn62>
Implementing Splice
Nicholas Dronen decided to try and implement splice in *PMCArrays, after
suggestions from Leo and Jonathan Worthington. I have found these Arrays
to be good starting points in the past. Good luck, Nick.
<http://xrl.us/hn63>
Optimize MinGW
François Perrad provided a patch making " Configure.pl --optimize " and
" Configure.pl --optimize=flags " work on MinGW. Jonathan Worthington
applied it.
<http://xrl.us/hn64>
Perl 6 Language
Object Model Pictures
Stevan Little posted the latest pictures of his MetaModel. Nathan Gray
thanked him and put out a quiet request for a diagram about roles.
<http://xrl.us/hn65>
Coersive Context
Juerd posted his thoughts about using types as context specifiers and
coercers. Reaction seemed interested but limited.
<http://xrl.us/hn66>
Perl 6 and Undefined Behavior
Nicholas Clark asked if Perl 6 was going to have any undefined behavior
or guarantee any sequence points. Larry does not want to have any
undefined behavior, but thinks that the reference implementations quirks
might be the definer for certain things. He did point out that junction
evaluation order is defined to be undefined.
<http://xrl.us/hn67>
Junctions, Patterns, and Function Maps
Luke Palmer posted another version of his fmap proposal which defines
junctions and hypers in terms of funtor maps.
<http://xrl.us/hn68>
Lazy vs Eager vs Something in the Middle
Yuval Kogman requested a nifty kind of asynchronous gather take which
would handle the threading automagically. I really like it.
<http://xrl.us/hn69>
" \(...) "
Ingo Blechschmidt started a long thread on the exact semantics
of C< \ > in the presence of arrays, commas, and parens.
