--disallow-untyped-calls allows calling values with Any type

The calls to f and ff below aren't rejected when using --disallow-untyped-calls, even though I believe that they should be:

from typing import Any

from non_existent import f  # type: ignore  # Not in the build

def g(): pass

def h() -> None:
    g(asdf=1)  # Error: Call to untyped function "g" in typed context
    f(asdf=1)  # No error reported, but this is untyped
    ff: Any
    ff()  # No error reported, and again this in untyped

At the very least the first call should probably be caught. If non_existent gets added in the build with no type annotations, it would start generating errors. However, I'd expect that adding a module to the build should result in fewer Any-related errors, not more.

Marking this a high priority since I've been bit by this twice in production code.

Riprodurre l'esempio Python dell'issue con --disallow-untyped-calls, quindi tracciare il modo in cui vengono controllate le chiamate attraverso valori importati e valori tipizzati esplicitamente come Any. Il lavoro è completato quando le chiamate a f e ff vengono rifiutate senza modificare la diagnostica esistente per g; il payload non indica alcun file sorgente o test da cui iniziare.
