Which in turn would make me think ref counting would be a
good idea.
It seems, that ARC is the only way. There were idea to make all
non-scoped (in my terminology) objects ARC-d, if they have
dtors. That
makes sense to me.
Interesting, we haven't explored that. The most problematic
implication would be that classes with destructors will form a
hierarchy separate from Object.

Yeah, that's a good point: How do you define a "class
with/without destructor", when they all derive from Object
anyways.
Necessarily, Object needs to have a destructor (even if it does
nothing) for any other sub-class to have them. Or vice versa, if
Object has no destructor, no subclass can have them?
So is it even possible to separate classes into two different
groups?
