If you want to use certain advanced language features, enable the appropriate extensions.
Your answers typify a level of comprehension of Haskell which appears to occupy the same brain space empathy would do. The whole POINT is that there are complex language features which have to be enabled if you want them: how does anyone know a priori in a new situation what to enable and what to disable? What side effects? What consequences?
I loved learning Haskell but to pretend it's syntactic simplicity translates to simple in all things is to misunderstand.
Gcc has a million compiler -W options do you think every C programmer knows them all? Do you think that every cat user knows why we joke about cat -v?
You have mastered Haskell and forgotten what lack of complete understanding means to anyone else. Mastering FORTRAN or pascal or lisp was trivial by comparison.
Mastering the underlying concepts of recursion, and tail recursion, and typing systems, and then integrating optional language features is not trivial.
There's a lot here I would like to respond to, but I'll limit myself to a couple points:
> The whole POINT is that there are complex language features which have to be enabled if you want them
Yes, "if you want them". If you value having a simpler language, don't use them. And Haskell is hardly unique in this regard. You've mentioned GCC, but I think the Babel transpiler is another good example.
> You have mastered Haskell and forgotten what lack of complete understanding means to anyone else.
I've managed to teach my daughter some Haskell, who had no prior exposure to programming languages whatsoever, so I doubt your assertion is entirely true.
The hardest programming language I ever learned was the first one. Each one after that was easier than the one before...until I got to Haskell. It was so different that I was forced to go back to a more fundamental understanding of the nature of code and computation and start from there. It felt pretty challenging, especially at first, but I think that had more to do with my perspective and experience coming into it than the language itself (and the fact that I had a family and career at that point didn't help).
