Oh yes so there is! But what is the rationale for what goes in those
two header lines, and what goes in the grey box lists? Why would
idioms be in the first place but not the second, and FAQ in the second
but not the first? Perhaps we could have just the grey boxes?

So if anyone knows of an interesting Haskell trick, and wants to write
about it, add a page!
It is
showed the Haskell98 solution for
exactly the same example, in their article `Infix expressions',
back in 2002:
http://www.haskell.org/pipermail/haskell-cafe/2002-July/003215.html
For ease of reference, here's their elegant solution:
infixr 0 -:, :-
data Infix f y = f :- y
x -:f:- y = x `f
