There are two different patterns for function signatures: the Hashtbl
pattern and the Map pattern. Both are "good", depending on the context.
Since I need both approaches I have come up with a little trick to get
the best of both worlds.
# let (~%) f = fun x y -> f y x
The ~% operator swaps the first and the second parameter in a function
call. The following is a trivial example of its use.
# ~% Printf.kprintf "Hello %s!" failwith "World";;
Exception: Failure "Hello World!".
