Re: unary "-" operator

I don't know if this is something that's been argued before, but I came across an interesting example of why the unary '-' is bad, while searching for reasons that single line comments are bad. A section involving the binary minus operator must always be bracketed, and as such will always have a '(' infront of it. That means that this example can never happen: infixl 0 --> (-->) x y = print x >> print y f = do { -5 --> 5; return()} Delete the space after the '{' and you have a problem. This can't happen if you don't have a unary minus. Bob
