That's kind of the point of having posblits in the first place,
As I argued previously, the only justification I can think of for postblit is for reference counting. The counters posted here were variations on reference counting, or could be done in terms of reference counting.
In fact, I think we could solve the postblit problems with const, immutable, and shared by dispensing with postblit entirely and providing some sort of compiler magic for doing ref counting.
