You said "deallocating unreferenced elements". I thought you meant 
elements unreferenced by the AA.

What I mean is, the AA isn't going to change implementations where it 
now deallocates values that may still have existing references. If 
that's the case, we can state that in the docs.


Removing a key does not deallocate the value that was removed. The 
value's lifetime is managed by the GC and will be alive until there are 
no references to that value.
