 * NOTE: static_pointer_cast might be unsafe (silently ignoring when node is
 * being used incorrectly), so using dynamic_pointer_cast (which would lead

 * performance hit since getter can be used very frequently.
 * Because of this, we might revert to static or even reinterpret cast in
 * the future...
