Good point. I've changed the method names to first()/last() and also made the wording in https://wiki.php.net/rfc/deque more consistently use first/last to avoid confusion. No, They're the same. front=start=bottom=first. Bottom was from SplDoublyLinkedList/SplStack, e.g. the bottom of the stack, top is where push() acts, etc. Front was how I was referring to iteration order. > In the "Why use this instead of array?” Section, the 3rd point seems cut off: > > Note that starting in php 8.2, array That should say "Note that starting in php 8.2, arrays that are lists (with no/few gaps) are represented in a more memory efficient way than associative arrays.". I've updated the RFC. Thanks, Tyson
