It's things like that that makes OCaml what it is. It supports OO even if you don't use it all the time, it supports imperative constructs. I remember reading in "Le langage Caml", by Xavier Leroy, that you should use an imperative loop over recursion if the loop is simple, and keep recursion for complex use cases, where it makes sense. That's not something you often hear from functional programmers, probably because the ones we hear are more obsessed with purity than practicality. But it's a great way to show OCaml's values.
