RE: [Python-Dev] Proposing a sys.special_exceptions tuple

A candidate implementation is up at SF. Patch # 1038256.

It uses the name 'special_exceptions' and includes SystemExit, MemoryError, KeyboardInterrupt and StopIteration (adding/removing exceptions from the list is easy, as is changing the name).

One version of the patch creates 'exceptions.special_exceptions' only, and the other version also creates a builtin.

Since we're trying to catch anything *not* special, is the intended usage something like this: try: func() except special_exceptions: raise except: altfunc() # handle non-special exceptions Raymond
