Well, (a) is your own conclusion, not mine; and Christian also has a tiny 
little patch that fixes (b) for standard Python on Windows (it's a 
miscalculation in Python's config that doesn't leave enough stack space for 
handling the traceback). I don't use it, because I know the symptoms, and 
can usually fix the problem before the stack trace finishes printing.

I love it too, but it gives you a whole bunch of entertaining new ways to 
get into infinite recursions.
