  • I still completely do not understand why it’s called a “Protocol” (well, unless you turn your head sideways and squint).

    I bet that’s a Smalltalkism. Since classes in Smalltalk tend to have so many methods, they are grouped into protocols, which are collections of methods of a single class, associated with a keyword phrase. Some protocol names are common and have agreed-upon meanings, such as number, observing, sequence or private.

    But I can’t bet too much on it, because the first MOP was part of the Common LISP Object System, not Smalltalk. (Smalltalk-80 was the first version to sport a MOP.)
