• #12677 和 #12889 实现了 Domain.DLS 的线程安全。

• #12924 和 #12930 提到了一个类型系统的错误和其修复方式（merged）:

module type S = sig
  type t [@@immediate]
end

type t = (module S with type t = int)
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(*
Error: In this with constraint, the new definition of t
       does not match its original definition in the constrained signature:
      Type declarations do not match:
         type t
       is not included in
         type t [@@immediate]
       The first is not an immediate type.
*)
