+		//		value. Foreign promises are converted.
+		//
+		//		If callbacks are provided and the initial value is not a promise,
+		//		the callback is executed immediately with no error handling. Returns
+		//		a promise if the initial value is a promise, or the result of the
+		//		callback otherwise.
+		// valueOrPromise:
+		//		Either a regular value or an object with a `then()` method that
+		//		follows the Promises/A specification.
+		// callback: Function?
+		//		Callback to be invoked when the promise is resolved, or a non-promise
+		//		is received.
+		// errback: Function?
+		//		Callback to be invoked when the promise is rejected.
+		// progback: Function?
+		//		Callback to be invoked when the promise emits a progress update.
+		// returns: dojo/promise/Promise
+		//		Promise, or if a callback is provided, the result of the callback.
