the isBlah is not optimal now it is just there and we cannot rewrite everything. I still think that is: is a nice way to kill some of the isPlague in Object. Stef
But I hate more isPlague in Object.
I think that plage mostly arises when people do not like to use Visitors / DoubleDispatch.
Conceptually the #is: message IS exactly the same, instead of doing a dynamic dispatch you write procedural code with if checks, no?
