[Python-ideas] Thoughts about implementing object-compare in unittest package?

Hey all, What are thoughts about implementing an object-compare function in the unittest package? (Compare two objects recursively, attribute by attribute.) This seems like a common use case in many testing scenarios, and there are many 3rd party solutions solving the same problem. (Maybe we can promote standardization by implementing it in the standard library?) Apologies ahead of time if this idea has already been proposed; I was not able to find similar posts in the archive. Best, -Henry
