Pextra_ty (p, extra)
are additional paths of types introduced by specific OCaml constructs. See below.

Pextra_ty (p, Pcstr_ty c)
is the type of the inline record for constructor c
inside type p
.
For example, in
type 'a t = Nil | Cons of {hd : 'a; tl : 'a t}
The inline record type {hd : 'a; tl : 'a t}
cannot be named by the user in the surface syntax, but internally it has the path Pextra_ty (Pident `t`, Pcstr_ty "Cons")
.
| Pext_ty
Pextra_ty (p, Pext_ty)
is the type of the inline record for the extension constructor p
.
For example, in
type exn += Error of {loc : loc; msg : string}
The inline record type {loc : loc; msg : string}
cannot be named by the user in the surface syntax, but internally it has the path Pextra_ty (Pident `Error`, Pext_ty)
.
