[Python-ideas] Re: Why do we have two obvious ways to create a simple data structure? Let's deprecate one.

It's not actually that, although that's a good point you are making. I found myself using both of them not because one is more useful in certain cases and the other in others in small and niche ways. Both of the times I just used the latest one that came to mind. The fact that two different classes in two different modules have similar enough APIs that one could easily substitute one for another or vice versa without second thought depending on which StackOverflow answer comes up higher in the search (to oversimplify) with very little breaking doesn't sit well with me at all.
