That's setting the bar rather high, isn't it? I appreciate that you
are talking about professionals, but working professionals whose
domain is Haskell programming should have long since mastered basic
Haskell, whatever we call "basic". Their daily work is intermediate
Haskell, with occasional detours into the advanced.
