In ThingLab, objects are constructed interactively by editing and making descendants of prototypes. An abstraction hierarchy is used that allows arbitrarily many levels of both parents and descendants, with the problem of objects with several parents being handled by the technique of merging. There is no distinction between classes and instances."
