/**
 * A RouteCollection represents a set of Route instances.
 *
 * This class provides all(*) methods for creating path+HTTP method-based routes and
 * injecting them into the router:
 *
 * - head
 * - get
 * - post
 * - put
 * - patch
 * - delete
 * - options
 * - any
 * - resource
 *
 * A general `addRoute()` method allows specifying multiple request methods and/or
 * arbitrary request methods when creating a path-based route.
 *
 * __call() forwards method-calls to Route, but returns instance of RouteCollection
 * listing Route's methods below, so that IDEs know they are valid
 *
 * @method RouteCollection withAssert(string $variable, string $regexp)
 * @method RouteCollection withDefault(string $variable, mixed $default)
 * @method RouteCollection withArgument($variable, mixed $value)
 * @method RouteCollection withMethod(string ...$methods)
 * @method RouteCollection withScheme(string ...$schemes)
 * @method RouteCollection withMiddleware(mixed ...$middlewares)
 * @method RouteCollection withDomain(string ...$hosts)
 * @method RouteCollection withPrefix(string $path)
