[Caml-list] example from manual FTBFS

[Hendrik Boom <hendrik@topoi.pooq.com>]

I took an example from 
http://caml.inria.fr/pub/docs/u3-ocaml/ocaml-objects.html

class amateur : object ('a)
  method play : 'a -> int -> 'a
end
class professional : object ('a)
  method level : int
  method play : 'a -> int -> 'a
end

and tried to compile it:

hendrik@notlookedfor:~/dv/ocaml/parse/priority$ ocamlc tt.ml -o tt
File "tt.ml", line 4, characters 0-5:
Error: Syntax error
hendrik@notlookedfor:~/dv/ocaml/parse/priority$

Those five characters are the word "class" on the second class 
declaration. But it's not the word "class".  If I leave that second 
class declaration out, it still complains at the same point, at the 
end of file after the first class declaration.

Evidently, I'm doing something wrong.

hendrik@notlookedfor:~/dv/ocaml/parse/priority$ ocamlc -version
4.01.0
hendrik@notlookedfor:~/dv/ocaml/parse/priority$ which ocamlc
/home/hendrik/.opam/4.01.0/bin/ocamlc
hendrik@notlookedfor:~/dv/ocaml/parse/priority$
