Well, Python 3000 is explcitly not intended as a platform for
arbitrary experimentation with feature invention (read PEP 3000).
I've gotten quite a bit of mileage out of borrowing from other
languages instead of inventing my own stuff, so I don't want to go out
inventing as a replacement of researching options that have already
been tried elsewhere.

But anything that makes the build explicit is going to be so much more
ugly. And I still think you're trying to solve the wrong problem.
