We could perhaps add structure-level substitutions to handle these
kinds of cases:

module L := List
module List = struct end
let test = L.map (fun x -> x + 1) [1; 2; 3]

module M := struct let map f x = f x end
let () = M.map (fun _ -> ()) 0

As in signatures, the idea would be that names like 'L' and 'M' bound
in this way would be internal-only, and would not appear in the
signature.
