I wouldn't be too worried.  If these things really must be learned in
some prescribed order, then we're all doomed - who here learned
Haskell as their first programming language?

Meanwhile, that fellow evidently didn't write any compiler in Haskell
at all.  Better a C++ program than a Haskell program that offends you?
