Ich leider noch nicht. Im Byob-Handbuch lesen wir:

"The idea of object oriented programming is often taught in a way that makes
it seem as if a special object oriented programming language is necessary.
In fact, any language with first class procedures allows objects to be
implemented explicitly; this is a useful exercise to help demystify objects.
The central idea of this implementation is that an object is represented as
a dispatch procedure that takes a message as input and reports the
corresponding method."

Was ist eine "dispatch procedure"? Gibt es dafür einen (für Schüler)
verständlichen Ausdruck?

Dank für Aufklärung.
