You missed the way Ada does OOP, and went completely overboard talking about generics.

As you can see from my comment history, I am quite aware of CLOS, Lisp variants and Dylan.

Last I checked, Ada does not have multimethods/generic functions in the sense of CLOS, Dylan and Julia. It has static function overloading, and single-argument dispatch, just like C++.
