If it helps, any argument can be turned into a small non-negative integer
with 6 s: s:@:(3!:1)@:< . If you want an M.-like adverb that applies this
transformation first,
M =: M. ( @:( 6 s: s:@:(3!:1)@:< ) )
But I imagine 3!:1 is pretty expensive, so you'd have to get a lot of
improvement out of M. to make it worthwhile.
