So it looks like gnus-article-part-wrapper passes the "N-th MIME handle"
and only that argument:

    (gnus-article-part-wrapper N FUNCTION &optional NO-HANDLE INTERACTIVE)

    Call FUNCTION on MIME part N.
    Unless NO-HANDLE, call FUNCTION with N-th MIME handle as its only
    argument. If INTERACTIVE, call FUNCTION interactively.

so I can do something like

    (gnus-article-part-wrapper 1 'mm-pipe-part)

which still requires manual input to the minibuffer of the command I
want the mime part piped to. This obviously doesn't work:

    (mm-pipe-part 1 "~/bin/pipe_to_tmp")

I guess I'm still foggy on exactly how to call HANDLE and how HANDLE is
named.

That's what I'll probably try next, but was hoping for a way to call
HANDLE in (mm-pipe-part HANDLE "~/bin/pipe_to_tmp") to make for a more
simple function. Also, I'd like to get a clearer idea about what HANDLE
is here, how it's named, called, etc.
