As Collin already pointed out, it sounds like you want PEP 362 to get into the stdlib. I have not made a big push to try to get my existing implementation into Python 2.6/3.0, but I plan to at some point.

Every time I read PEP 362, I get lost in the details. When you get around to working on it again, could you add a bunch of examples? That would make it much easier to tell why we want all those objects and attributes.

FWIW, Isaac's version of bind() that returns a regular str->object dict is all I've ever needed in my own code.
