Re: So, what the heck is a continuation anyway?

I wonder if that is always true. ;)

Consider: Perl code calls into Expat or Tk.
Expat or Tk of course uses the C stack.
Expat or Tk calls back into Perl. 

Now, how do you build a continuation that takes into account the *C
stack* being used by Expat or Tk? That's one of several (!) issues
keeping continuations out of Python.
