587	CR: expt should signal error on domain error	felix winkelmann		"`expt` returns +NaN when called with a negative first argument and a non-integer second argument. With a full numeric tower this would be a complex number, but those are of course not supported in the core system.

I suggest signaling an error in this case. This might break existing code that relies on +NaN being returned.
