Eq instance for Chan

already have a consumer and then duplicating it if another (and every additional) consumer would be added. But without Eq it is not possible to check if there is Chan already in a list (and I hope Eq would compare just Chan and not its content). Is there some other way to achieve this? Mitar

Re: Non-exhaustive pattern match(es) warning in lambda functions

solution. But this is a form of closed world assumption. When you write _ as a case you in fact use this assumption. But when you later on extend the world with some new case, this assumption could not really hold anymore. Mitar ___ Glasgow-haskell-users

if it would be added. Obviously I am for it. ;-) I think n should be scoped for the whole the class definition, everywhere, not just parameter and return values types. If somebody would define the same name for it for some local definition, GHC should make a shadowing a variable warning. Mitar
