/**
 * Creates a shape that merges multiple objects together. Note that intersecting fixed properties
 * with a `recordShape` (or other generic mapped object keys) is not supported and will break in
 * many ways.
 *
 * @category Shape
 * @example
 *
 * ```ts
 * import {intersectShape, checkValidShape} from 'object-shape-tester';
 *
 * const myShape = intersectShape(
 *     {
 *         a: '',
 *     },
 *     {
 *         b: '',
 *     },
 * );
 *
 * checkValidShape({a: 'hi', b: 'bye'}, myShape); // `true`
 * checkValidShape({a: 'hi'}, myShape); // `false`
 * ```
