Well, not that my opinion counts for much, I'm +0 on it.  It's conceptually nice
as you say, but I doubt I (or many others) would use it much, and hanging it off
the set builtin doesn't feel totally satisfactory to me (but I don't have a
better suggestion).

I hope you find some more firmly opinionated responses to your idea.  :)
