Minor refactor + typing info

[Carreau]

This adds mypy configuration to ignore voici (untyped), and slightly refactor to pass some kwargs explicitely.

It also pleases mypy.

Hi, @Carreau! I'm just helping @steppi a bit with code review on some of the pending PRs and I had a look at the changes here, and they look good on my end. Question: does adding from __future__ import annotations to the top of the file make sense too (and maybe with an accompanied isort rule as well after #156), considering it will be mandated with future Python versions someday? I don't think we're using anything complicated here that will break later.

[Carreau]

Thanks for the review.

I tend to avoid unnecessary from __future__ import annotations, I found that unless necessary they tend to hide bugs in older versions of Python, in particular at runtime if you use get_type_hints.

More particularly, from __future__ import annotations make annotation lazy and allow you to write things that are invalid – typically you can start using list[...] in types, but this is invalid on earlier python.

As for isort, no objections, but I thought the precommit would take care of it ? If not we can just add it.

Thanks for the info, TIL that future-annotations can get us invalid types on earlier Python versions like that. I guess we would have to enable the isort rule before pre-commit starts to apply it across the codebase, but I suppose that's something to do in a separate PR.

Looks good. Sorry for forgetting about this.

[Carreau]

No problem, thanks for the review and merge.
