2.0 should see some reverse iterators #117

Closed rtheunissen closed 6 years ago

rtheunissen commented 6 years ago

Recently there's been talks about a array_keys_first and array_keys_last, which made me think that there should be a way to achieve this for associative types, whether it's a getKeyAt function or a view of the keys.

After some more thought, I don't believe there is a use case here that can't be achieved with a traversal over a reversed copy.
