I understand that, which is why I said "From the standpoint of Perl 6". : >We can certainly make it the default that a routine is not going to : >do anything fancy with continuations unless it is explicitly declared : >to allow it. : : Can't do that. There's no way you can ever really know that, since : any function or method you call might take one. Forbidding it is : going to be problematic as well, since then we hit performance issues : in guaranteeing that. Well, Leo asked for hints, and I basically said Perl has no problem sending them. If Parrot has a problem receiving them, that's another matter. :-) Larry
