Yes, it is necessary, but how much? Can we do it with implicitly 
generated library code?

I'm pretty sure the answer is "not much" and "yes", but I still 
need to ponder the details. I think the typeinfo for a class good 
enough for dynamic cast could be about half the size we have now.

Though like I said, a lot of the stuff we have now is cool stuff, 
so I don't want to miss it entirely, it could be behind another 
pointer.
