acorn-babel

acorn-babel is not supported outside of babel usage. Do not expect support if you use this in your own applications.

Deviates from acorn in the following ways:

• JSX support via acorn-jsx
• ES7 Abstract references
• ES7 Async/await
• ES7 Exponentiation operator
• ES7 Object rest/spread
• Babel Playground features
