Array.count is a function taking an instance; I’m not sure I agree it would be terribly confusing… then again I run in Xcode with the quick help pane open so I see the doc comments for every type, property, and function as I move around the code. It’s quite handy :)

I could see including memory in the name (or something similar) if we want to be extra clear about it.


Ultimately the type’s size in memory is a property of the type so it seems clear that is where it belongs (being careful not to steal too much of the namespace of course).
