Array - What's the use case here? (And I'm not being snarky or even critical.) My usage is generally lists for small stuff where I don't care about performance, and pandas/numpy for analysis. So maybe array is either if I don't want numpy, or if I am doing something real and large and list performance would truly be a problem? Also, I looked for a PEP to answer these questions and couldn't find it. (The one I found was very old). Or any stats on performance improvements?
