]> Hi, << class type m_t = object end class type ['a] c_t = object constraint 'a = #m_t end module type T = sig type t class c: [t] c_t end;; Characters 125-126: class c: [t] c_t ^ The type parameter t does not meet its constraint: it should be #m_t as 'a = < .. > >> I don't understand why this signature is rejected : I would say it's ok, since one cannot write a module with this signature without having t meeting the constraint... How can I workaround this ? thanks, damien ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
