Hi,
Similarly to polymorphic variants, is there a way for object signatures to
be merged by type name? Consider the example at the end; I'm wondering if
it is possible for the declaration of 'foobar' to be something along the
lines of 'val foobar: int -> int -> < foo_t; bar_t >' instead of needing to
explicitly list all the methods in foo_t and bar_t.
Thanks in advance for your help!
Best regards,
Dario Teixeira
module Test:
sig
type foo_t = < a: int >
type bar_t = < b: int >
val foobar: int -> int -> < a:int; b: int >
(* val foobar: int -> int -> < foo_t; bar_t > *)
end =
struct
type foo_t = < a: int >
type bar_t = < b: int >
class foo a = object method a: int = a end
class bar b = object method b: int = b end
let foobar a b =
object
inherit foo a
inherit bar b
end
end
