Demo for teamwalnut/rescript-urql#232

Run yarn start to test

The problem does not exist when the package.json does not contain the resolutions line, since this will install an extra copy of wonka (@4) in the urql folder. However, this might cause issues when something in the application actually uses the other installation of wonka.

To reveal the problem, adding the following snippet to package.json will force yarn to install only the version 5 of Wonka.

  "resolutions": {
    "wonka": "5.0.0-rc.1"
  }
