ok I just looked it over. I think (4) isn't really viable, the cache 
pointer storage overhead is probably too much (in addition to some 
complex issues). I don't really like having a macro (so (3) basically) 
and I think there are issues with non-static caches, I don't know 
specifically though. obviously (1) doesn't work. (2) is exactly what I 
was thinking specifically for rbtree. IMO the only useful options are 
(2) and (3). I would say maybe implement (2) first and if you want 
macro-generated ZST allocators they can wrap whatever that Box ends up 
being.

I agree
