Fixes #714, pretty sure it doesn't work in Python 3.7, though, so this will have to be after we drop support for it (which will be soon). |
|
Would ifdefing it with sys.version_info be considered acceptable to get it included sooner? Alternatively ifdefing an import of Literal from typing_extensions? |
|
3.7 is EoL in 2 months, so I'll probably just remove support in the next release |

Mypy can't currently detect that an "Unset" is falsey. By changing the bool annotation in types.py, we can give it the help it needs
