You're asking for an answer that assumes we're using the same definition of "inward". The meaning of that term is unclear in the presence of continuations.

    "inward" as in overloading on return type.

    Where are continuations used in Perl 6? I don't see any language features that explicitly do that. As you said, resuming an exception is simply returning since the stack is not unwound. Closures are starting-off points that take their environment from the actual caller. No co-routine constructs or "live" label references, etc.

    Anyway, my question as it stands, is as has been mentioned on this thread and referenced posts. Or, is the whole conversation overlooking Something Important?
