[fetter-devel] Verrazano Speedup

[Christian Lynbech]

I just discovered that the fix needs a fix, like the following
version:

        (defmacro push-end (value lst)
          `(setf ,lst (nconc ,lst (list ,value))))

Without the explicit setf, the value change may get lost as nconc is a
destructive function. At least with SBCL, I suddenly had no
definitions derived from macros after applying the fix.
