(1) Why are we biasing the programmer to expect one thing (the function is wrong) and not the other (r is wrong)? I.e., would the programmer benefit from inclusion of the "alternative view" as well?
The error message isn't really pointing blame, it's just saying, "Yo, I'm stuck at this stage of the inference algorithm so I'm sending the ball back into your court." But you do have a point. That said, after a certain amount of experience with ghc, one learns to quickly scan the errors for key bits. The 'alternative view' repeats essentially the same info twice and including it doubles the amount of spew-out. -- Kim-Ee
