OCaml Adds `List.take` and `List.drop`

One of my small issues with OCaml is that the standard library is quite spartan. Sometimes it misses functions that are quite common in other (similar) languages. One such example are functions like drop, drop_while, take and take_while in the List module.1 What’s weird is that the similar Seq module features all those functions since OCaml 4.14. I believe it was Haskell that populirized them. ↩

Learning OCaml: Verifying tail-recursion with @tailcall

How can you be sure that an OCaml function you wrote is actually tail-recursive? You can certainly compile the code and look at the generated assembly code, but that’d be quite the overkill, given there is a much simpler way to do this.
