Found on Lobste.rs: Mark Karpov writes yet another Haskell vs. OCaml for old time’s sake. I found it worth a read and a mention here.
p.s. He spends a bit of time in the intro lamenting the lack of a conventional Unicode string library for OCaml, and I feel that pain acutely, especially since I’m the author of an unconventional one, i.e. the Ucs_text module in my Orsetto project.
