Can we also get some feedback on specialization, please?

It should cover all the conversions outlined in the latest SotS.  There 
are a few known things that don't work quite right yet, things like:

  - Nonstatic inner classes and local classes (we're close on this, though)
  - super-calls inside generic methods

But, it should be enough to write an ArrayList-like class that is 
generic in any-T.

To run it, just clone and build the valhalla repo (make images), and use 
that as your JDK.
