Subject: Nested modules with equal types

is there a way in OCaml to define nested modules where a type t of the
inner module is defined as equal to the out type of the same name?

For example, I would like to define a file containing

type t
module Inner :
  type t = t

but I get the error
Error: The type abbreviation t is cyclic
which kind of makes sense. Can I somehow refer to Outer.t in the Inner
module? (Outer.t does in fact not work either).
