It wasn't a rhetorical question. I wanted to open discussion on your contribution, and wanted to start with what folks on this mailing list are most familiar with.
I'm not a Commons Collection maintainer, but I'm curious if you could describe your implementation in a few sentences and how it differs from the current DualHashBidiMap implementation. Is it faster than other implementations? Does it have a lower memory footprint by sharing key and value objects between two underlying HashMaps? Does it implement its own HashMap interface implementing its own Map data structure? Can you name one or two scenarios where your implementation would be preferred over the existing implementations?
