                Scala Collections Proposal
              
          
    Collections Redesign Proposal

I'm going to start off by motivating what I'm doing here.  And I want to be clear that I'm not "dissing" the existing collections implementation or anything as unproductively negative as that.  It was a really good experiment, it was a huge step forward given what we knew back in 2.8, but now it's time to learn from that experiment and do better.  This proposal uses what I believe are the lessons we can learn about what worked, what didn't work, and what is and isn't important about collections in Scala.
This is going to start out sounding really negative and pervasively dismissive, but bear with me!  There's a point to all my ranting.  I want to be really clear about my motivations for the proposal being the way that it is.
