The where clause works well for Haskell, because there are no order of
evaluation issues.  Because of side-effects, the where clause in ocaml
would usually just end up being confusing.  Think of a multi-page
expression with a where clause at the end.  Not that this is good code,
but it would sure be easy to miss.  It would probably cause the same
kinds of problems that C's 'break' causes in switch statements.
