I've never used C++, but I've heard that C++ is not simply an
extension to C, but is extra-C, in that the syntaxes are different.
This is as opposed to CLOS and (again, I've heard) Objective-C.

If this is indeed the case, then C++ can't be written in C, but
requires preprocessing.  CLOS is written in CommonLisp, which is one
reason that it can be quite portable.  This seems to me to be a
minus for C++ from both an engineering and a human-factors point of
view.
