 * Core class used to implement a REST request object.

 * Contains data from the request, to be passed to the callback.
 *
 * Note: This implements ArrayAccess, and acts as an array of parameters when
 * used in that manner. It does not use ArrayObject (as we cannot rely on SPL),
 * so be aware it may have non-array behavior in some cases.
 *
 * Note: When using features provided by ArrayAccess, be aware that WordPress deliberately
 * does not distinguish between arguments of the same name for different request methods.
 * For instance, in a request with `GET id=1` and `POST id=2`, `$request['id']` will equal
 * 2 (`POST`) not 1 (`GET`). For more precision between request methods, use
 * WP_REST_Request::get_body_params(), WP_REST_Request::get_url_params(), etc.
