I just realized that this interface would suffer from a significant
drawback: it would trigger COW when iterating over immutable arrays,
defeating the shared-memory optimization provided by OPcache.
An interface like new ReflectionReference($array, $key) would be free from
the issue. Combined with get_defined_vars() and the (array) operator for
objects, we can inspect any PHP data structure or scope also this way.
