This may sound like a bizarre request, but I feel I can't be the only one.

I can give a +1 that this would be useful. Here's an annoying case I've run into that doesn't even require partial functions: fiveDiv :: Int -> Either String Int fiveDiv 0 = Left "Can't div by 0" fiveDiv n = Right $ 5 `div` n and the test cases are: fiveDiv 8 === Right 0 and isLeft (fiveDiv 0) Now the string itself ("Can't div by 0") is marked as an uncovered expression. This trivial case could easily be covered but: a) I've run into this frequently enough in more annoying cases, and b) it feels more idiomatic to write a test that doesn't care about the contents of the string (and the test doesn't need to change if the string changes) Tom
