Impossible because you can't define new operators in C++ (only overload
existing ones). Besides, noncommutativity in GiNaC is a property of the
objects, and the ordinary '*' operator is used for both commutative and
noncommutative products (that's handled automatically). Symbols are
commutative by default, but you can subclass your own, noncommutative
symbols.

For more information, see the GiNaC tutorial, section "Non-commutative
objects".

Bye,
Christian
