Why is

parsed as Pexp_construct rather than Pexp_ident ?  [This is Ocaml 4.01].

Perhaps to be consistent with
    type bool = false | true

Quite :

# type drole = true of drole | false of drole*drole | HAHA;;
type drole = true of drole | false of drole * drole | HAHA
# false (false (true HAHA, HAHA), true (true (true (true HAHA))));;
- : drole = false (false (true HAHA, HAHA), true (true (true (true HAHA))))

"true" and "false" being defined as keywords by the OCaml lexical
conventions ( http://caml.inria.fr/pub/docs/manual-ocaml/lex.html ),
it seems perfectly reasonable not to parse them as identifiers.

(That the implementation is overly permissive in accepting their use
in exotic way is another matter.)
