I fear I'm not qualified to answer that, and I hope somebody else picks up the topic. I'm even less qualified, but I have this feeling that the whole thing is tied up in the event/threading side of things. But I don't actually know anything. Xi, basically, the specification for Events and Threading is still very much in its draft stages: http://perlcabal.org/syn/S17.html You can see that it mentions an Event Loop, but there's no information about it yet. So assuming that I'm correct, the best answer we can give you is The plans for that part of Perl 6 are still on the drawing board.

Re: Two questions on Perl 6 functionality
I still have several points unclear, this is my sample:
###
class Base {
method toHash() {
return {};
}
}
role FooBar {
has $.foo is rw;
has $.bar is rw;
toHash.wrap({
my $hash = callsame();
$hashfoo = $self.foo;
return $hash;
});
}
class Compose is Base does FooBar {
}
my $obj = Compose.new(foo='foovalue', bar='barvalue');
my $data = $obj-toHash;###
1: It tells me toHash is not defined, as the role actually don't has that.
2: It seems that wrapping will affect the closure globally, but I only want
class with specific role has specific modification.

In Perl 6, you do that with wrapping:

Hi,

Perl 6 has traits, so you can write for example
class A {
method x() is rw { ...}
}
to indicate that it's an lvalue routine (though I don't think it's
implemented in Rakudo yet).
Where can I get the doc about that? By reading apocalypse?

RE: Two questions on Perl 6 functionality
Very subtle implementation, I'm trying to understand those things. Thanks!
