/**
Simple string literal for native JS text literal substitution.

`literal(string, context)` where:
- `string` is a string that may contains literal string variables or functions wich be evaluated.
- `context` is the variable context object. Any reference to `this` in the `string` argument will 
refer to the `context` object.

Example:

literal('Hello ${this.name}. Shout ${this.word.toUpperCase()}!', {
  name: 'Willy', word: 'Waller'
})
Will return "Hello Willy. Shout WALLER!"
*/

function literal(string, context) {
  const func = new Function(`return \`${string}\``)
  return func.call(context)
}
