This fixes potential issues with callable types where there are a
different number of argument names compared to argument types. These
malformed callable types might have caused crashes.

This may address #4599. Even if the issue remains unfixed, future
tracebacks could be more useful due to an assert that I added.

Did you not find a small repro for a test yet? Even though you know how to fix it?

The new assert caused a few failures in existing tests.
