=head1 Perl 6 Summary for 2005-10-10 through 2005-10-18 All~
Welcome to another Perl 6 Summary. Sadly, this week's summary is not brought to you by cookies as I already finished them. Sadder still, it is also brought to you a week late. On the plus side, Mike Doughty's "Haughty Melodic" is quite good. =head2 Perl 6 Compilers This was a shockingly high volume fortnight for p6c with 5 different threads on it! =head3 Feather: A Retrospective Juerd thought that now would be a good time to evaluate the usefulness of feather to the community.

Stevan Little proposed that class methods should not be inheritable. This sparked a large debate which Stevan apparently lost (by his own omission). http://groups.google.com/group/perl.perl6.language/browse_frm/thread/8f66ca405155cc97/dcc9daf13767acfd#dcc9daf13767acfd Google Groups : perl.perl6.language =head3 C< ++ > should mean C< ++$_ > Juerd wonderd about making more operations (like C<++>, C<+=>, and C<x=>) all operate on $_ by default. Response seems mixed but favorable. http://groups.google.com/group/perl.perl6.language/browse_frm/thread/9ef9173d6ab586b8/490144d7dd7da86f#490144d7dd7da86f Google Groups : perl.perl6.language =head3 C< $_ ~~ bool::true > Ilmari Vacklin noticed an error in S04 centered aroud given/default. Luke Palmer and Larry agreed that it was a problem. http://groups.google.com/group/perl.perl6.language/browse_frm/thread/93a3220242a26dc7/0a05e33dff79c0a8#0a05e33dff79c0a8 Google Groups : perl.perl6.language =head3 zipping several arrays Mark Reed wondered how to zip several arrays given that zip was an infix operator. Luke Palmer explained that it was actually a listfix operator like C<,>. http://groups.google.com/group/perl.perl6.language/browse_frm/thread/3cb8bb881983b559/21152a256284c5e8#21152a256284c5e8 Google Groups : perl.perl6.language =head3 New Class Sigil ¢ Larry announced that there would be a new class sigil, namely ¢. This allows you to write functions like C< sub sametype (¢T $x, ¢T $y) {...} >. People generally like the idea but not the charcter. I must admit that I agree with people. http://groups.google.com/group/perl.perl6.language/browse_frm/thread/f026e181a6a599ac/66354fc1198e61d4#66354fc1198e61d4 Google Groups : perl.perl6.language =head2 The usual footer To post to any of these mailing lists please subscribe by sending email to <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]>, or <[EMAIL PROTECTED]>.
