Subject: [PATCH] Preserving signature in "module.run" state (U#50049)

Add unit test for _call_function on signature aligning named arguments

Add unit test for _call_function routine for unnamed positional arguments

Remove redundant docstrings

Add different test function signature with the same outcome

Replace standalone function with lambda-proxy for signatures only
