And more correct as I would assume that

I don't understand the existence of that phrase, and the fact that it
doesn't give a warning when used in numerical

Actually, given Damian's and my conversations last night, it looks like
the first return arg from want() is going to be the context after all

I think we're pretty much agreed on this point, but I have a tangential
question about want().
