module Exp : sig ... end

Row fields

module Rf : sig ... end

The module `Rf` has been introduced in Ast_helper with OCaml 4.08.0 (as row_field type switched to a record representation). Moreover, even the current Ast_helper.Rf.inherit_ (OCaml 4.10.0) misses the ?attrs flag.

module Of : sig ... end

With constraint

module With : sig ... end
