Fix mypy_mypyc crash caused by "complex" interaction - #6169
Merged

Conversation
The type of Num.n is `complex`, though it can in practice also be an `int` or a `float`, and we case on the actual type to determine which sort of mypy ast node to use. In #6114, promotions were disabled in `isinstance` checks, which caused mypy to decide that the `isinstance` checks for int and float won't match. Fix this by giving the value the type object instead of complex. Typeshed *does* actually annotate `n` as `Union[float, int, complex]`, but mypy simplifies that into `complex`. (It does *not* do this simplification for local variables with such an annotation; see issue #6168.)

(mypy_mypyc is currently completely busted until this goes in.) |

Argh! There's still a failure left that causes some tests to fail. I've also opened #6170 for running mypyc in CI. (The way this snuck in was that I ran |
