Err, no. return is much stronger. It goes to the caller of the sub.
Yield would be relative to a much tighter scope.
I think Randal would reject this, but if we make it an error to
have a last/next/redo reach outside of a visible lexical scope, then
last,next,redo would be 'weakest', followed by yield, return, die
(and whatever is used for exceptions.)
