This is a little off-topic so I'll be brief.  When using -X Python
never even creates the class exceptions, so it isn't really a
conversion.  It just uses string exceptions and tries to craft tuples
for what would be the superclasses in the class-based exception
hierarchy.  Yes, class-based exceptions are a bit of a performance hit
when you are catching exceptions in Python (because they need to be
instantiated), but they're just so darn *useful*.  I wouldn't mind
seeing the -X option go away for 1.6.
