Expected Behaviour

System.register('myBundle', [], function (exports) {
	'use strict';
	return {
		execute: function () {

			const a = exports('a', window.config ? 1 : 2);
			const b = exports('b', 1);
			const c = exports('c', 2);

		}
	};
});

Actual Behaviour

System.register('myBundle', [], function (exports) {
	'use strict';
	return {
		execute: function () {

			const a = exports('a', window.config ? 1 : 2);
			const b = 1 ;
			const c = 2);

		}
	};
});
