Why remove this? exp is a bit cryptic in the function name and a line of documentation here is useful.

What about tests for a=big number and n=big number, a=float, n=float?

Can do, but the n=float case won't work because the algorithm can only compute integer powers

I know it won’t work but I wanted to see how it fails. Does it raise a ValueError? Does it behave like pow() does. Testing how things work if half the battle. Watching them fail is just as cool.

OPTIONAL: Adding a timeit benchmark would be a nice addition. Visitors love to see the side-by-side bakeoff.
