No. Use length == 0. O(1) length is always supported for all collections. > OTish: What are your thoughts on a bimap implementation and a > child/sibling or general tree implementation as part of dcollections? I haven't the slightest what a bimap is :) I am not an expert in collections or data structures, I just reimplement things I have understood. My implementations are basically copied from my algorithm book, and refined as much as I can do. That being said, if you have any implementation of a tree or hash, it should be easy to insert into dcollections. If you have ideas for other collection types (i.e. other than Map, Set, Multiset or List), then I can look into that if you point me at an implementation or have one of your own. I purposefully left out multi-map because I've never had a huge use for it, and it seemed like a awkward thing to create an interface for... -Steve
