Bug information

• Babel version: 6.3.26
• Node version: v0.10.36
• npm version: v2.5.1

Description

I am using React with Closure Compiler. If you write in JSX the codes with cast like

var foo = /** @type {Foo} */ (this.props.bar);

Babel with the transform-react-jsx plugin converts it to the code:

var foo = /** @type {Foo} */ this.props.bar;

The parentheses around this.props.bar are removed.

As the result, compiling the output js with Closure Compiler always fails by missing parentheses around the cast.
