Actually I just some weeks ago discovered monad {
and now it took me a quite a while to see how your nice expression work.
Might be we should have a cartesian product competition!
My favorite ,"_ _1 "_1 _ is due to the fact, that I began to understand
the rank conjunction with this expression.

(actually I just today discovered your question!)

Do you find it more or less impressive that J has a primitive for cartesian
product?
cart =: {@:,&.<
The monad { is neat but this formulation doesn't demonstrate the
loop-abstraction that yours does.
