It seems there are many toothing problems with Deno. I just tried stuff from their blog (https://deno.com/blog/v1.8):

    $ deno run --unstable --allow-write=output.png https://raw.githubusercontent.com/crowlKats/webgpu-examples/f3b979f57fd471b11a28c5b0c91d0447221ba77b/hello-triangle/mod.ts
    Download https://crux.land/2arQ9t
    Download https://crux.land/api/get/2arQ9t
    error: Import 'https://crux.land/api/get/2arQ9t' failed: 404 Not Found
        at https://raw.githubusercontent.com/crowlKats/webgpu-examples/f3b979f57fd471b11a28c5b0c91d0447221ba77b/deps.ts:4:0

(A dependency got removed?)

Another one:

    $ deno run https://deno.land/v1.8/permission_api.ts
    error: An unsupported media type was attempted to be imported as a module.
      Specifier: https://deno.land/v1.8/permission_api.ts
      MediaType: Unknown

(The site is a 404 returning status code 200... just... why?)
