IMHO, users of GiNaC should not reply on the internal representation of
algebraic objects (even that op(nops()-1) thing is suspicious to me), because
that representation has changed, and will change sometime in the future.
Extensions to GiNaC in the form of new classes, however, may benefit from
or even require access to the internal representation, in which case the
C++ "friend" mechanism can be used.

Bye,
Christian
