Basically, there is no difference to function/subroutine call. The difference is just that there is no "call stack": the dynamic context for a call is created on the heap and is garbage-collected when it is no longer accessible. A continuation is just a reference to the state of the current dynamic context. As long as a continuation remains accessible, you can return to it as often as you like. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum -- http://mail.python.org/mailman/listinfo/python-list
