Hm, looks like the style of type annotations I copied relies on being evaluated lazily, i.e. requires at least python 3.14, where that lazy evaluation was introduced.

Hence the failing CI checks on python < 3.14.

This also means that the same style inside _build_umac() must also fail on python < 3.14.
Perhaps that code isn't invoked in the CI though because libnettle isn't found or similar.

No, this is wrong.

Apparently, with python < 3.14 these annotations are already lazily evaluated/ignored in a context like in _build_umac() but not at global scope ...

Updated the pull-request with a fix for older python versions.
