Add support for the `void` operator in templates and host bindings. This is useful when binding a listener that may return `false` and unintentionally prevent the default event behavior. Ex: ``` @directive({ host: { '(mousedown)': 'void handleMousedown()' } }) ``` BREAKING CHANGE: `void` in an expression now refers to the operator Previously an expression in the template like `{{void}}` referred to a property on the component class. After this change it now refers to the `void` operator, which would make the above example invalid. If you have existing expressions that need to refer to a property named `void`, change the expression to use `this.void` instead: `{{this.void}}`.
Adds support for the exponentiation (`**`) operator in templates Ex: ``` @component { template: '{{2 ** 3}}' } ```
