I guess it is there so as to obey the CL definition which says:

    When result-form is evaluated, var is bound and has the value nil.

If that's the case, then the let-binding can be moved so it only
covers the `,(nth 2 spec)` part of the code.  Personally, I'd be happy
to disobey the CL specification in this regard since I find it
completely silly.
