From the standpoint of Perl 6, I hope to hide continuations far, far away in a galaxy long ago. No wait, wrong movie...
Which is swell, but Perl 6 is only one of the languages we care about. Ruby does, and while it's not exactly one of the primary targets, scheme and lisp are heavily laced with them.
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.
