The solution to this and similar problems is to define more protocols like the iteration protocol [1], but for showing objects, accessing their properties etc.

The solution to this and similar problems is to define more protocols like the iteration protocol [1], but for showing objects, accessing their properties etc. If libraries and tools rely on protocols instead of using built-in objects then we would be able to plug any kind of data structure implementing the required protocols into any kind of library that takes advantage of those protocols.
