 * This type helps resolve complex TypeScript types in simpler readable types
 *
 * - Take a layered complex type (extending multiple types, using generics, inheriting etc.)
 * - Create a dummy type via Prettify (type Dummy = Prettify<ComplexType>)
 * - Hover with the mouse on the dummy type to see the "resolved" type
