I'm with Rob on this one: '+:' is not simply another way of saying '+'. It should always do the right thing wrt. PoLS (Principle of Least Surprise).

If compatibility with Haskell (i.e., low precedence) leads to incorrect results (i.e., *surprise*), then let's not be compatible.

Let's add an explanation to the manual that warns Haskell programmers to expect to "get their sums right with Q". ;-)
