If you're going to use a lot of such magic DEVICE components, that
could be a win.

I'd favor either a keyword argument or :function as a magic marker to
be inserted in FIRST position, followed by a function designator (and
additionally, parameters to curry?). Unless of course, you
symmetrically accept a FUNCTION in first position to denote a
"recognize if this matching rule applies".
