If the UTM Theorem states there's a u such that u(e,x) = f(x) where both
are defined and both are undefined when either is undefined, is that
interesting or surprising to anybody?
The identity function is valid for u and forces that e = f. Job done.
Am I missing something? Isn't it just trivially deducible from the
identity introduction axiom when you have it, which we assume when we
haven't fully formalised our discussion of computation.
