type hints
I started to add type hints to the register
ed test functions (see !201 (merged), !200 (merged), !199 (merged), !198 (merged), !197 (merged), !196 (merged)). While these type annotations are ignored by the interpreter, they allow nice additional tooling (IDE-Features, static type checking, automated test data generation with hypothesis
, et. al. (!185 (merged))).
I think, the benefits outweigh the things, type hints do to function signatures, so I'd like to add them whenever there is some time to do so. If you have any objections against such, we should discuss that @luenensc and @palmb .
