Bracketing for a moment what keyword might be used, a thing I like about this syntax is that it can work for multiple names naturally.  E.g.

    expose Symbol as x, y, z

Or with a different word:

    define Typevar as T, S, R

For things like namedtuple that need more arguments, you'd need to use functools.partial to create the single argument callable to match the syntax.

"expose" sounds like it is taking something hidden or private and
exposing it to the public. It doesn't give any hint that it takes the
name T and uses it as an argument to Typevar. I would take it as

take the (possibly internal or private) thing Typevar, and bind it to
the name T

with no hint that Typevar was being called.
