Huh? The only thing that is not decidable in Haskell's type system is
polymorphic recursion. Apart from that you do not need any type
annotations (except in order to get around Haskell's monomorphism
restriction, but that is a different story).

Type classes do not break type inference. Just read Mark P. Jones's
papers.
