Unpacking NamedTuples gives Any type

[yellowjello]

Is your feature request related to a problem? Please describe.
Currently unpacking NamedTuples results in Any type for the unpacked elements.

Example:

from typing import NamedTuple

class Something(NamedTuple):
    blah: str
    hah: int

ntpl = Something("yes", 1)

(a, b) = ntpl # a and b are Any

Describe the solution you'd like
It would be great if the behavior is the same as unpacking regular tuples where it gives the types of the unpacked elements.

This is now addressed in version 1.1.63 of Pyright, which I just published. It will also be in the next release of Pylance.
