Summary
Minimal reproducer:
def foo(initial_arg: str, *args: str) -> None:
...
foo(*["a", "b", "c"]) # No argument provided for required parameter `initial_arg` of function `foo` (lint:missing-argument) [Ln 4, Col 1]
foo(*[1, "a", "b"]) # No argument provided for required parameter `initial_arg` of function `foo` (lint:missing-argument) [Ln 4, Col 1]I'd expect first the invocation to type check because the splatted args have compatible types to cover both the first argument and the var args.
