I noticed that Peter Golde got the first source drop of the PowerCollections posted… Peter is just starting this project, so there is plenty of room for your feedback.


In an unrelated note, Peter Sestoft and co just posted a very complete version of their C5 project.  Sestoft’s project is much more complete and is a parallel library to System.Collections.Generic library rather than the PowerCollections library which is a natural extension of the BCL library. 


As for a more detailed compare and contrasts, I’d be interested in your opinions and maybe we can get the Peter’s to comment on each others efforts ;-)
