Looks like OCaml was not your first language. I suspect you are coming from a imperative language background.

OCaml is slow? and your recommendation is to use Haskell instead... That doesn't compute well if we were to assume that you are writing some compute-intensive tasks for which (unoptimized non-C language can be "slower".

It more likely the case that students hate whatever languages the university teaches in place of language-de-jour. (Just read the reviews of SICP on Amazon).

And yes there are pages on the internet that are older than 2006, so what? No one goes "Pffft.. this is 300 years old.." when they come across Newton's Principa.
