示例2: CONST_EXPR

import {CONST_EXPR} from 'angular2/src/facade/lang';
import {StringMapWrapper} from 'angular2/src/facade/collection';
import {EventEmitter, ObservableWrapper} from 'angular2/src/facade/async';

import {Directive, Ancestor, onChange} from 'angular2/angular2';
import {forwardRef, Binding} from 'angular2/di';

import {NgControl} from './ng_control';
import {Control} from '../model';
import {setUpControl} from './shared';

const formControlBinding =
    CONST_EXPR(new Binding(NgControl, {toAlias: forwardRef(() => NgFormControl)}));

/**
 * Binds an existing control to a DOM element.
 *
 * # Example
 *
 * In this example, we bind the control to an input element. When the value of the input element
 * changes, the value of
 * the control will reflect that change. Likewise, if the value of the control changes, the input
 * element reflects that
 * change.
 *
 *  ```
 * @Component({selector: "login-comp"})
 * @View({
 *      directives: [formDirectives],
 *      template: "<input type='text' [ng-form-control]='loginControl'>"
 *      })
