I've wanted this for a long time, but I don't think Guido's ever been in favor of this.

Could function decorators be used for this? Something like:

Possibly so, and that's kind of neat.

@attachtoobject(Account) def deposit (self, v): ... del deposit

The decorator couldn't delete the binding of 'deposit' in the current namespace, however.

Couldn't you play sys._getframe() tricks inside the decorator to do this?
