Arch Linux

Description:

The `mypy` package depends on `python-toml`, however upstream has switched to the `tomli` package (which is available as `python-tomli` in `extra`).


Additional info:
* package version(s): mypy 0.920-1
* config and/or log files etc.:

(In a clean chroot, after `pacman -S mypy`)

```
