YAML support

💡 Ideas

I've recently discovered the usefulness of YAML. I've used a package on npm that allows for the importation of .yaml files, and it works really well. But I think there should be some notation that allows for YAML code directly in a JS file. Consider this:

const json = {
  "hello": "world",

  "foo1": {
    "bar": true,
    "baz": false
  },
  "foo2": {
    "bar": true,
    "baz": false
  },

  "blockquote": "Hello World\n\t—The Computer"
}

/* In YAML, it would look like this */

// three hyphens to begin YAML
const yaml = ---
hello: world
foo1: &foo
  bar: true
  baz: false
foo2: *foo
blockquote: |
  Hello World
  	—The Computer
...
// three dots to end YAML

These two variables are identical.

You could use a tagged template:

const foo = yaml `
hello: world
foo1: &foo
  bar: true
  baz: false
foo2: *foo
blockquote: |
  Hello World
  	—The Computer
`;

where yaml is provided by some library.
