A source operand to a VLIW instruction – this can be a variety of things, so we have a pointer to an abstract base class and a number of derived concrete classes for the different kinds of operands. When we parse the operand, the type may be determined, or if it is just a name, we will have to wait to a later pass to resolve what the name refers to. At that point, the ‘Named’ object created in parsing will be replaced with the actual operand type
