Subject: [Caml-list] "in" question

I've been working through Jason Hickey's introduction to Objective Caml and
don't quite get why the "in" is necessary in this construct:

# let sum i = let sum2 j = i + j in sum2 ;;
val sum : int -> int -> int = <fun>

If I leave out the "in" I get a generic "Syntax error":

# let sum i = let sum2 j = i + j ;;
Characters 31-33:
  let sum i = let sum2 j = i + j ;;
                                 ^^
Syntax error

I'm sure it's something fundamental about scoping I'm missing.  Please
enlighten me.

Thanks,

Monty
