Subject: [PATCH 3/3] Fix mypy failures

Due to slyp adding `-> None` annotations, some unannotated collection
types are flagged. This does not add broader annotations, only the
ones needed to get back to a healthy mypy state.

Minor changes are included to generator function tests, but most parts
of the library are unchanged.
