// This file is used for TypeScript compilation to ES5 only.
// Since this file is not included in the compilation to ES6, it is an error
// to <reference> this file from other sources.
// Instead it is referenced by the rootFilePaths option to the compiler.
// We also want the following typings to be available only when compiling to
// ES5, because they are redundant with lib.es6.d.ts.
/// <reference path="../angular2/typings/es6-promise/es6-promise.d.ts"/>
// es6-promise.d.ts chose a different name for this interface than TS lib.es6.d.ts
// Generic Type Alises are in TS 1.6 (https://github.com/Microsoft/TypeScript/pull/3397)
// So we cannot write:
// declare type PromiseLike = Thenable;
// Until then we use a workaround:
interface PromiseLike<T> extends Thenable<T> {}
// Extend the ES5 standard library with some ES6 features we polyfill at runtime
// by loading traceur-runtime.js
// These are mostly copied from lib.es6.d.ts
