I definitely think that -1# should be parsed as a single lexeme. Presumably it was easier at the time to do it the way it is, I don't remember exactly.
I'd support a warning for use of prefix negation, or alternatively you could implement the Haskell' proposal to remove prefix negation completely - treat the unary minus as part of a numeric literal in the lexer only. This would have to be optional for now, so that we can continue to support Haskell 98 of course.
yes please! odd that I look forward to such a minor change in the big scheme of things, but the current treatment of negation has annoyed me more than any other misfeature I think. John -- John Meacham - ⑆repetae.net⑆john⑈
