Summary

• Handle Symbol in transform-es2015-computed-properties
• Disallow ...[ & ...{ inside object destructuring

http://tc39.github.io/tc39-notes/2017-05_may-23.html#16ih-why-allow-bindingpattern-for-bindingrestparameter-for-object-rest-maybe-we-should-just-allow-identifiers

// Invalid
( {...{}} = {} ); ( {...[]} = {} );
let {...{}} = {}; let {...[]} = {};

• Split transform-export-extensions into transform-export-namespace and transform-export-default plugins
• Move transform-numeric-separator to Stage 2
• Move transform-class-properties to Stage 3
  • Change the default transform to use Object.defineProperty and loose option to use assignment (this.a = 1)
  • Use configurable: true
• Change es2015-template-literals to use .concat by default and concatenation in loose mode.
• Remove deprecated jsx pragma check in transform-react-jsx
• Remove preset-flow from the preset-react (there was confusion on why type syntax was allowed, and it also made it incompatible with preset-typescript
• Add --config-file CLI flag to explicitly pass a config location
• Move babel-standalone into the repo (another form of this used to be babel-browser)
