I have an alternative idea that probably is easier to implement:

Add an quick fix for the warning issued by GHC that some methods in an instance arent implemented (No explicit method nor default method for `fmap') that just adds stubs for all those methods, using " = undefined " as implementation

Adding = undefined quickfix might be useful for a top level type signature without a defenition as well (The type signature for `f' lacks an accompanying binding).
