Current status of prototype / call to action

[Brian Goetz]

Maurizio has recently put back a number of changes that round out the major 
features outlined in the SotLv2, and this is a good point for those who have 
been sitting on the sidelines to try it out.  What we need most right now is 
for people to try it out on real code bases, and share their experience with us.

If you are having trouble building it from source, let us know.
