Hello! Why isn't there an option to control whether HPC, the Haskell Program Coverage, will consider derived instances "coverable". I'm using it and my top level coverage is 52% while my expression coverage is at 92%. Looking carefully we see that most non-tested top level definitions are derived Show, Eq and Ord instances that I always derive for most data types (as this is a library). I think it is nice that it recognizes class instances, but there should be a flag to ignore at least the derived ones. Am I missing something? Thanks! :) -- Felipe.
