Just a suggestion I thought I'd throw out... There's a restriction in the language implementation on exactly what can go the left of an augmented arithmetic expression. For example: >>> a = 3 >>> a **= 2 is ok, but: >>> class Foo(): ... def __init__(): ... self.a = 3 ... def __ipow__(self, x): ... self.a **= x ... >>> Foo() **= 2 File "<stdin>", line 1 SyntaxError: illegal expression for augmented assignment Now unless I've done something stupid above (always a possibility :o) the implementation seems a bit strict (is it really a *syntax* error? - I am not sure exactly what the restriction is). This may seems like a small issue, but operators can really help with making embedded DSLs in Python - they give quite a bit of "wiggle room" to invent a syntax that is compact and intuitive. The restriction above cuts into that (OK, so it's still a small issue... :o) Cheers, Andrew -- http://mail.python.org/mailman/listinfo/python-list
