Serhiy: Yes I was also thinking it might be time for a common helper function.

Milap: I think changes like you mentioned (originally by me) would be fine. Another variation was done for Issue 10838: revision 10b0a8076be8, which expects each object that is not a module object (e.g. not from “import sys”), rather than expecting each object that is a function or class defined in the module. It might depend on the particular circumstance which technique is superior.
