Great, then it looks like we have a winner!

Based on previous experience with defmethod's dispatch, I suspect that
the main bottleneck may be in the time it takes to turn the arglist into
a proper list and then to pass it to `apply` (those two steps happen
within the "wrappers" built by `defmethod` and which decide which method
to call).
