Not without bringing back the behaviour whereby the exception
you want to reraise can get clobbered by another exception
before you get a chance to reraise it.

Python's way of dealing with this is to save the current
exception on entry to every function and restore it afterwards.
That would be an unacceptable amount of overhead for Pyrex,
given that the overwhelming majority of function calls do not
need this to be done.

My suggestion is to think of another way to achieve whatever
it is that PyProtocols is trying to do. If you can provide
some more details about that, I may be able to help.
