Hmm. . .
def default_inputhook(statement):
try:
aliased = sys.aliases[statement]
except KeyError:
return False
else:
aliased()
return True
sys.aliases = dict(exit=sys.exit, quit=sys.exit)
sys.inputhook = default_inputhook
I think Walter's idea may have merit (although I believe the input hook should
be passed whole statements, rather than individual lines).
Cheers,
Nick.
