I still don't see how you get a rank on m.

You can't use an x argument, because then you'd be doing dyad m}. And in the gerund form,

(v1`v2)} y is (v1 y)} (v2 y)

and you can't put a rank on the selection operation that way either.

But of course, there is a way of giving rank to m - you just have to
change the expression (use gerund form of } which extracts m out as an
argument, for example).
