Yeah, I suppose that is the case :)  I was stuck in FP mode (and
without-generator-expressions mode; I use those two functions in my
own code all the time)

I'm afraid those names would inspire people to write code like this:

alltrue(bool(x) for x in someIterable)

I think the "true" in the function names might make people think it
constrains the type to be a bool, which, if it resulted in code as
above, would definitely be unfortunate.
