I don't agree here. As someone who's only ever dabbled with Haskell, I found its error-messages pretty cryptic, no better than C++. Perhaps they make more sense

I don't agree here. As someone who's only ever dabbled with Haskell, I found its error-messages pretty cryptic, no better than C++. Perhaps they make more sense to someone with significant Haskell experience. For what it's worth, I believe modern C++ compilers give much better error messages than older ones.
