yep this is annoying. there is a flag in GHC to warn you about such missing methods: -fwarn-missing-methods
Agreed, and it's inconsistent with modules. For instance, this is an error: module M (a) where {} ...but this isn't: class C t where {a :: t;}; instance C Bool; I'd like to request a "-ferror-missing-methods" flag. Actually, it would be nice if every warning flag had an "error" flavour. -- Ashley Yakeley, Seattle WA
