Perl 6 Summary for 2005-06-21 through 2005-06-28
All~
Long time no see... err, write... uh, read... um... this. Yeah, long
time no this. As Piers hinted, two weeks ago I moved. Moving sucks. For
those of you who care, I am still in Cambridge, for those of you who
care more, I think you misunderstand the summarizer/summary reader
relationship. Essentially it revolves around summaries, and the summary
of my move is Cambridge to Cambridge.
As Piers noted last week, this is a low volume high action week. In no
small part do to the hack-a-thons. Last week's was in Austria, this
week's is near Toronto. Perhaps some nice soul who was actually at these
hack-a-thons will summarize it when it is over.
Perl 6 Compiler
Patrick announced that PGE now supports grammars and more built-in
rules. He even offered to field requests for built-in rules (although he
would prefer patches).
<http://xrl.us/gkev>
Caller's Context
Gerd Pokorra wanted to know how to determine if his sub is called in
void context. He conjectured that want might fill his wants. No response
yet.
<http://xrl.us/gkew>
Self Hosting Goals
Millsa Erlas explained that one good reason for Perl6 to be self hosting
is that it would allow the people who love it most (Perl hackers) to
hack on it. The theory being that low level languages like C
unnecessarily narrow the field of contributors (especially those that
only know perl). Some concerns were expressed over confusion about the
language Ponie should be written in. No one disputes this... C.

Parrot
Indexing Hashtables
Klaas-Jan Stol asked for a clue bat with respect to indexing hash tables
in PIR. Joshua Juran and Leo each took a swing.
<http://xrl.us/gkey>
Parrot Loses with Fedora Core 4
Patrick reported that Fedora Core 4 and Parrot don't get along well. Leo
suggested a possible solution. No response from Patrick.
<http://xrl.us/gkez>
Default Method Resolution Order
Roger Browne wondered what the default MRO order was. Leo provided the
answer: left-to-right, depth-first, discard all but the last occurrence
of duplicates, divine intervention.
<http://xrl.us/gke2>
Win32 Tests Failing
Craig the Last-Nameless-One posted a list of failing tests and problems
on Windows. Leo provided a few answers.
<http://xrl.us/gke3>
Method Inheritance Needs Perl Loving
Leo announced a perl job for the interested: method inheritance in the
PMC compiler. This naturally led to discussion of numerical hierarchies.
I was a little disappointed the quaternions got mentioned, but
Hamiltonian and Surreal Numbers were left out. Honestly, where are our
priorities.
<http://xrl.us/gke4>
Tracing and Debugging Pain
Matt Diephouse posted a general description of the problems he was
having with tracing, debugging, and GC. Warnock might apply in a day or
two.
<http://xrl.us/gke5>
Segmented Context and Register Memory
Chip posted a partial reply to Leo's context and register overhaul
patch. Andy Dougherty responded to some of Chip's finer points. If you
are interested in the nuances of C's pointer pain, this thread makes an
interesting read.
<http://xrl.us/gke6>
Improving Parrot's Test Framework
chromatic wants to improve parrots test framework by stealing ideas from
Test::Class. He wants to know if anyone else is interested in this.
<http://xrl.us/gke7>
setattribute Fails with Multi-level Inheritance
Roger Browne opened a ticket describing an error with setattribute when
several layers of inheritance are used.
<http://xrl.us/gke8>
Register Allocation Bug
Leo opened a ticket for a problem with improper control flow tracking.
Bill Coffman wondered whether the new register design had been
implemented yet.
<http://xrl.us/gke9>
Pass by Value PMCs
Klaas-Jan Stol mused that the new calling conventions could be leveraged
to allow passing PMCs by value.
<http://xrl.us/gkfa>
Parrot Fall Down Go Boom
Matt Fowles reported a segfaulting parrot that passes its tests. Sadly,
no one solved his problem in the 4 hours between his posting it and
writing the summary.
<http://xrl.us/gkfb>
Perl 6 Language
You Know That, But You Go On
As Piers noted, arguments about " ./method " vs " .method " continue.
Like Piers, I don't like "./". I guess I was the only person who did
like $^ as the invocant. Ah well, I guess I will just go on
summarizing...
<http://xrl.us/gkfc>
Binding Functions
Piers wanted to use a Ruby idiom involving rebinding functions. Damian
told him that he could, but also pointed him to " wrap ".
<http://xrl.us/gkfd>
OO Questions
BÁRTHÁZI András posted a question about method calls in Perl 6. Juerd
and Piers provided answers.
<http://xrl.us/gkfe>
Autoload and $_
Last week's thread about AUTOLOAD continued. It still seems to be
fishing for some official decision.
<http://xrl.us/gkff>
Magic Mutators and Proxies
Sam Vilain wondered if he could make proxies behave like he wanted to.
Luke Palmer explained, yes, but he would need to use binding instead of
assignment.
<http://xrl.us/gkfg>
Quasiquoting and PPI
Brad Bowman asked how Quasiquoting and PPI would interact with the AST.
Autrijus posted a some explanation, and Adam Kennedy cleared up some
terminology.
