The situation with "self" is a bit different. When you
do something like

    foo.method(args)

it's obvious that something is being done *before* the
call, i.e. looking up the 'method' attribute of foo, and
that step has the opportunity to manufacture and return
a callable having the appropriate number of args.

However, with

    x -> TypeVar()

it looks very much like whatever is bound to TypeVar
is being called directly, before anything else happens.
For that not to be the case would be a rather higher
order of weirdness, IMO.
