(What the OP wants was also proposed a few weeks back in comp.lang.c.
But that was only within nested functions, so if H is inside G, and G is

F. Apparently Lisp allows this...)
Well, not directly, but it can be simulated with the condition system
(equivalent to try/except) or with throw/catch, which is similar but
doesn't use exceptions.
But my point was that in Lisp you don't need to do this, because you can
write a macro that expands into a return *in place*, without calling a
separate function, and this eliminates the problem entirely. Since
Python doesn't have macros I was looking for the next-best solution, but
there doesn't seem to be one. Oh, well...
Thanks,
