Description

I suggest you add Range, Min, and Max typing to check if a number is inside a range or something like that.

def example(range_example: Range(int, 1, 5), min_example: Min(int, 5), max_example: Max(float, 5.4)):
    pass

That would be useful and really nice to have.

Research direction

Start by reviewing issue #1304's proposed Range, Min, and Max annotations and its int/float examples. Determine the intended static-checking semantics and whether this belongs in typing; done requires an agreed design and documented behavior, since no target files or tests are specified.
