And to be absolutely clear - existing interface does not support it too
- we iterate over every single hash entry, and then over every single
item in the chain (if it exists). I can create the same for the tree -
it is not complex at all, but it is not the most optimal solution, and 
since I remove several entries, I think it is not that bad to remove a 
bit less and optimize 'iterate over all object' case a bit.
