FWIW, it's pretty common to sometimes omit spaces around arithmetic 
operators +, -, *.  This was common enough to derail the idea to make 
negative integer literals be lexed ( "-", no space, numeric literal ). 
So you'd have to fight that battle.

I think spaces around all operators sounds nice in a new language; I'm 
not sure about Haskell.
