I came up with a totally rubbish solution to this: define an "infix-ising"
operator like so which lets you use "long" operator names made of plain

  let (%) a b = b a

  let add a b = a + b
  let addf a b = a +. b

  5 %add 6
  10. %addf 12.

This is not a serious suggestion though, since it totally breaks under
lots of situations, mostly involving precedence. Still, I suppose there
might be a use for it somewhere.
