But you started it! You said that to the uninformed, C++ looks simpler
than Ada, but that with deeper understanding, the opposite becomes
apparent. I invited you to show me some code which demonstrates this.

I don't know Ada, and I don't feel like learning it right now, but I
think I could follow an example you post. So show me an object which
requires a constructor and user-defined assignment operator in C++,
but only a simple declaration and no such operator in Ada. Or if I
misunderstood, just show me *something* where Ada's object model lets
you do away with things that C++ requires.
