I don't see why.

``this'' is just a const pointer to the object being passed.  Therefore
a class member is just this->'d.  What problem di g++/gcc have in this
area?

That is correct.  We find that initial purchasers of Comeau C++ will
sometimes call up about this, but often never call twice as they get
used to it since C++ has many characteristics which diverts the energy
normally spent in debugging into other areas of the programming cycle.
Nevertheless, this is something that we spend time on solving with the
ports of Comeau C++ we do.  For instance, under UNIX we have something called
CCsdb, which allows you to use to C++ names as is.
