Consistency is a reasonable argument I think ^_^. But also it means we get to avoid all the confusing evaluation rules; what's `2 ** 3 ** 4` equal to, what's `-1 ^ 2` equal to, etc etc. JS had a lot of confusion solving these, and ended up with some interesting restrictions as a result (for example, you have to parenthesize the LHS if it's a negative value, to avoid any ambiguity).

`pow(X, 2)`, on the other hand, is 100% unambiguous all the time.
