#587: CR: expt should signal error on domain error

Description changed by felix:
Old description:

> 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.

New description:
`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.
