    Nrev-fix

    Identity function for nrev.

    Signature: (nrev-fix nrev) → nrev'

    In the logic, this simply sets:

    nrev' := (list-fix nrev)

    In both the pure and optimized implementations, this is a no-op that just returns nrev unchanged.

    This is a fast operation. It is generally useful to call (nrev-fix nrev) in your function's base case, to avoid needing true-listp hypotheses.

      (list-fix nrev$a))

    Function: nrev$c-fix$inline

    (defun nrev$c-fix$inline (nrev$c)
      (declare (xargs :stobjs nrev$c))
      nrev$c)
