Ultimate OOP

Why can't there be a programming language that supports the Ruby idea of making everything an object, but at the same time use C++ features like copying with marshaling (I don't know whose idea it was to make everything in Ruby a pointer, but it makes making hard copies a bitch), multiple inheritance and constructor overloading. Furthermore, why can't said language be made to compile down to assembly like C and C++, rather than the vast majority of Object Oriented languages which run in an interpreter?

Except of course with all the ints and floats and such being considered objects, and all the arrays being essentially vectors.
