PTAL

A while ago when I wrote this, I forgot(!) that there is no exponentiation
operator in JS. Rick Waldron caught this while working on the test262 porting.

It's a trivial fixup.

lgtm

Amusing that slipped through initial code review, I guess it's easy for eyes to
glaze over when reading tests.
