Expected Behaviour

export { x as "'x" } from 'x';

function a () {}
function b () {}
export { a as "'a", b as "'b" };

System.register(['x'], (function (exports) {
	'use strict';
	return {
		setters: [function (module) {
			exports("'x", module.x);
		}],
		execute: (function () {

			exports({
				"'a": a,
				"'b": b
			});

			function a () {}
			function b () {}

		})
	};
}));

Actual Behaviour

System.register(['x'], (function (exports) {
	'use strict';
	return {
		setters: [function (module) {
			exports(''x', module.x);
		}],
		execute: (function () {

			exports({
				'a: a,
				'b: b
			});

			function a () {}
			function b () {}

		})
	};
}));
