Deno 1.8.2
exit using ctrl+d or close()
> import { emptyDir } from "https://deno.land/std@0.91.0/fs/mod.ts";
Uncaught SyntaxError: Cannot use import statement outside a module

seems like import should probably work on cli without having to do something like this (which also didn't ultimately work)

Issue 2:
Hi there! I've ran into this error when running the ✨ new ✨ HTTP server via Deno.serve.

The error does not occur when importing serve from /std/http/mod.ts regularly.

Error:

Watcher File change detected! Restarting!

============================================================
Deno has panicked. This is a bug in Deno. Please report this
at https://github.com/denoland/deno/issues/new.
If you can reliably reproduce this panic, include the
reproduction steps and re-run with the RUST_BACKTRACE=1 env
var set and include the backtrace in your report.

Platform: linux x86_64
Version: 1.25.0
Args: ["deno", "run", "--unstable", "--allow-net", "--watch", "repro.tsx"]

Steps for reproduction:

Create a tsx file with the contents:

/** @jsx h */
import { h, ssr } from "https://crux.land/nanossr@0.0.1";
Deno.serve(() => ssr(() => <p>Hello world.</p>));

Run the file with RUST_BACKTRATE=1 deno run --unstable --allow-net --watch repro.tsx.

Update (save) the file to trigger a file change.
