HTML tag autocomplete/autoclose in template literals

[nbbaier]

I don't know if this is feasible, but it would be nice to have autocomplete or autoclose for HTML tags inside template literals. Currently, I type out the html I want, highlight it, and type `. That's fine, but could be improved!

An ideal experience for me would be template tags in the stdlib:

import { css, html } from "https://val.town/v/std/tags"

const style = css`
h1 {
  color: red;
}
`

const  markup = html`
<h1>Hello world</h1>
`

coupled to something like this (for linting / completions): https://marketplace.visualstudio.com/items?itemName=bierner.lit-html

it looks like codemirror has some support for it: https://codemirror.net/examples/mixed-language/
