The NeXT implementation of Objective-C after version 0.9 of their OS
is an independent implementation.  Moreoever, it is based upon GCC
from the Free Software Foundation and therefore falls under the
free software policy of FSF.

NeXT's object library is significantly different from that of 
Stepstone and the various IC-Paks.  I believe that IBM implementation
is a port of NeXT's implementation, but I am uncertain how much of
the NeXT code remains in the IBM version.

The latest FSF newsletter, as I remember, mentioned that version 2.0
of GCC would compile Objective-C (I assume this ability is derived
from the NeXT GCC).  Reflexively, version 2.0 of NeXT's compiler will
apparently compile C++.

So let's watch the world get smaller and happier and less religious
about languages.  I hope to see whether Objective-C and C++ can be
mixed along the lines suggested by Brad Cox or if it just isn't as
elegant as we might think.
