I love this list. We can go off on a ridiculously long tangent, simply
because I said that it's only *usually* best to put imports at the top
of the file. We all agree that it normally is indeed best to hoist
them, and here we are, arguing over measurement methods on whether or
not there's ever any benefit to importing inside a function.

Yep, the Cheshire Cat was right. We're all mad here!
