Answer 1

It seems that you are referring to Common Lisp / CLOS -style generic functions which do multiple dynamic dispatch. C++ does single dynamic dispatch with methods but only single static dispatch with functions. So the answer is no. C++ doesn't support this at the moment. There have been proposals along the years to add it into the language but that hasn't happened yet.
