Log: Revision 1.6 2003/07/28 23:18:04 lauerc
Log: Class ExpressionTuple is defived from new class Operand now.
Log: The object and operand members are of type Operand now,
Log: which means they can be VariableOperands, ConstantOperands and
Log: ExpressionTuples.
Log: The attribute operation is of type Operation now.
