Behold: ``` python def f(a: Optional[str], b: Optional[str]) -> bool: return a == b ``` We get this beautiful error with `--strict-optional`: ``` error: Unsupported left operand type for == (some union) ```

Maybe not obvious, but #1766 was a reduction of this issue.

No longer gives an error. I think this was fixed along with #1766 by #1836.
