O'Caml

Good day, fellow /prog/raiders.
I am currently learning O'Caml, what should I pay attention? What is Bad and what is Good on this language?

So you can do stuff like

let rec fact n = if n=0 then 1 else
 let n = n*(n-1) in fact n   (* <<-- For haskell, let n = n*(n-1) would not make sense. *)

Basically, you don't force recursive definitions every time you use let. Also, you don't have to make up new variable names all the time.
