Yes!  This is beautiful, semantically rich, and poetic.  These are the 
things that drive re-understanding of code written by groups of 
developers.  I would LOVE to see this capability in Erlang.

If I was really concerned about it I could then define my dyadic `each` 
and do:

F `each` [ItemsX, ItemsY].

...where F is a function of two variables.
