		#### `props(Object obj)`

		Accepts an object and waits for all promise values to resolve before returning. Returns
		a new object with values from the resolved promises.

		```js
		const P = require("extends-promise");

		P
		.props({
		x : P.delay(100, 'a'),
		y : P.delay(50, 'b'),
		z : 'c'
		})
		.then(res => console.log(res.x));
		```

		This method can be especially helpful when combined with destructuring as a way of returning
		named tuples.

		```js
		P
		.props({
		x : P.delay(100, 'a'),
		y : 'b'
		})
		.then(({ x, y }) => console.log(`x: ${x}, y: ${y}`));
		```
