It already is -- to __getitem__.
Having it go to something else just because you're in a function
definition is asking for trouble. What should happen in the following
case?
b=dict(strict=check1, lenient=check2, normal=check3)
def foo(a:b["normal"]): pass
Should it really look for some special method on b (or b's type) just
because it is in a signature context? Today, the annotation
expression would evaluate to check2, and I'm not looking forward to
figuring out all the corner cases on when that wouldn't happen.
