deno: const enum error clarification

This error appears after I switched to Deno 1.4.1 and fixed all the import type errors.

---

Skillz@Home Discordeno % deno run --allow-net --allow-read --unstable debug.ts
error: Uncaught ReferenceError: RequestMethod is not defined
    return runMethod(RequestMethod.Get, url, body);
                     ^
    at Object.get (requestManager.ts:124:22)
    at createClient (client.ts:44:41)
    at debug.ts:10:1

  get: async (url: string, body?: unknown) => {
    return runMethod(RequestMethod.Get, url, body);
  },

Also of note VSC shows 0 errors

Alternative Fix: (to just removing const)

Reason(By Kit ❤️): const enum are not supportable in a --no-check situation, and so in Deno 1.4.0+ we switched on the isolatedModules flag with --unstable to help folks ensure their code was “no check” safe.

Can we get a better error message for this please. Confused me like crazy! Although im always confused so… hahaha
