Obviously, it wouldn't succeed today, since int doesn't have __adapt__ and
str doesn't have __conform__. But why would you intend that they not have
them in future?
And, why do you consider adaptation *not* to be typecasting? I always
think of it as "give me X, rendered as a Y", which certainly sounds like a
description of typecasting to me.
