I think I have to call *bzzzzt* here. This is a common technique used during debugging. Insert a 1/0 to force an exception (possibly causing the running program to drop into pdb). I think you have to leave that in.

Many tests rely on this, and I have changed them from something like:

try: 1 / 0 except: ....

to

try: a = 1; a / 0 except: ....

But I know that it's a major source of incompatibilities, and in the final code I'll enabled it only if user demanded it (through a flag).
