That is an interesting result (even aside from the main result here, I'm not sure what python is doing such that `copy.copy(a)` has different performance from `copy(a)`!)

But python is slow, and nanos are short — unless there's a noticeable impact on the _overall_ performance, then prioritizing flexibility and compatibility are more consistent with the goals of the library. Does that make sense?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,958878760
