Wirth, in accepting OO for Oberon, said that it's simply ADTs under
another name.
When I first looked into OO about 1984, once I finally understood what
was going on, I didn't find anything new, except that the mechanism used
made the code less readable than if composition had been used. I
suspected that the OO people made up new terms for well established
concepts such as type (class) and subprogram (methods) to mask this lack
of original content. I later learned that class came from Simula, but
have yet to learn any earlier use of method or message for subprogram or
call.
