Hello,

Does anyone know if it is possible to specify a default definition for an associated type synonym? When I tried:

class A a where
  type B a = a

GHC (version 6.9.20080309) told me: "Type declaration in a class must be a kind signature or synonym default". However, when I look at the parser I see no way to specify such synonym default. Is this possible?



Thanks,
Zé Pedro
