support scripts using module

[quinn]

from mdn docs:

https://developer.mozilla.org/en-US/docs/Web/API/Document/currentScript

The Document.currentScript property returns the <script> element whose script is currently being processed and isn't a JavaScript module. (For modules use import.meta instead.)

i'm basically doing:

<script type="module">
	import { thing } from './thing.js';
	thing(me());
</script>

Ok, import.meta isn't helpful here. It looks like there is an open issue on the spec for this:
