I've been looking at Snit recently and there are definite benefits from being able to use delegation -- it allows the combination of objects from Snit with other object-like commands in Tcl (which there are definitely quite a few of).

I believe XOTcl could possibly benefit from this extra style. Naturally it would be really easy to do with filters and the unknown mechanism (as I was thinking of doing with Tk at one point), but perhaps there could be some use for an "official" approach to that. I'm not sure if this would be seen as polluting XOTcl or making it overly complex (I still believe in keeping things as simple as possible). Possibly it could be provided as a pure-XOTcl capability.

Just a thought.
