Re: Prefix negation

Pardon me - I was explaining the intuition rather than the translation. -x is translated to negate x but as far as fixity, you have to appeal to the 0-x notion. The basic idea is that the precedence of unary and infix - are the same in this way. I did a brief search of the old haskell committee mail, but I don't have the definitive message about unary minus around anymore as far as I can see. We seem to have finally given up on the debate by Haskell 1.3. John
