...guish two objects of
class HwMode if they have different names, regardless of what sets of
predicates they contain. One way to think of it is that the name of the
object would serve as a tag denoting the hardware mode.
In the example of the AddReg instruction, we could define two modes:
def Mode64: Mode<[...]>;
def Mode128: Mode<[...]>;
but so far there would not be much more that we could do.
2. To make a use of the mode information, provide a class to associate a
HwMode object with a particular value. This will be done by having two
lists: one with HwMode objects and ano...

I agree with the complexity, but I would
