Thank you SO much for doing this. It has always irked me that doing
something like marking a block NO_SCAN has the cascading effect of
making all callers impure, which is stupid because using, e.g., built-in
arrays by definition interacts with the GC, so why the hangup about
explicit interaction with the GC?

I say this is definitely the right way to go.
