This is what type annotations might look like: https://github.com/networkx/networkx/pull/4014

@fmagin You got it, `typing.Hashable` is the right way. In my pull request, I did want to make sure that `Node` was hashable, which is why I did: ```python Node...

This works on 3.7+. It can be fixed for 3.6, but there's no point in doing the work unless this will be accepted soon.

Okay, thanks for clarifying. I took the liberty of reverting my changes to these functions for the time being. Here's a comparison class variable functions with member variable functions, and...

So what's the plan with this? It would be nice not to have to rebase continuously or redo this work years later :)
