I don't know if this made sense to anyone after I posted it in the
middle of the night. What I want to do is throw a exception but not have
*my* function body in the stack trace:

def throwException(condition):
    if condition:
        raise AssertionError in parent_stackframe

def foo():

I'm thinking that the trick has something to do with setting up a trace
function or maybe it just isn't possible. I've done similar tricks
before but perhaps not this particular one...
