Cannot use Dict.t<json>

[Exegetech]

Using rescript@11.0.0-rc.3 and @rescript/core@0.4.0 with bsconfig.json

{
  "name": "playground",
  "sources": {
    "dir": "src",
    "subdirs": true
  },
  "package-specs": {
    "module": "commonjs",
    "in-source": true
  },
  "suffix": ".bs.js",
  "bsc-flags": ["-open RescriptCore"],
  "bs-dependencies": ["@rescript/core"]
}

Below works

@unboxed
type rec json =
  | @as(false) False
  | @as(true) True
  | @as(null) Null
  | String(string)
  | Number(float)
  | Object(Js.Dict.t<json>)
  | Array(array<json>)

But below doesn't work

@unboxed
type rec json =
  | @as(false) False
  | @as(true) True
  | @as(null) Null
  | String(string)
  | Number(float)
  | Object(Dict.t<json>) // <--- here
  | Array(array<json>)

The compiler gives error

This untagged variant definition is invalid: Case Object has a payload that is not of one of the recognized shapes (object, array, etc). Then it must be the only case with payloads.

It'll work if you use Js.Dict.t instead.
@cristianoc I remember we were talking about this before, but I can't find the issue anymore.

I'm having a look at this soon, I think it's about us not looking up aliases currently.

Yes, but that's weird since it is just an alias.

This should do it: #6394
