How do people do this?

I have:

    (defun yank-pop-back (&optional arg)
      (interactive "*p")
      (yank-pop (if arg (* arg -1) -1)) )

With `yank' at C-y, `yank-pop' at M-y, and then
the "yank-pop-back" above as C-M-y, it is very
easy to yank and then iterate back and forth.

The elaborate stuff with ARG isn't needed to
use with the setup I just described.
However remove it, it won't work iterating back
and forth!

    (error "Previous command was not a yank") in yank-pop

Must be an interface mismatch?

Hey, if it works, don't fix it, right :)
