Updated State of the Lambda

[Brian Goetz]

We do go a few bridges in another direction, as you saw -- but in my opinion 
the _ placeholder is indeed a bridge too far for Java.  (Works fine in Scala 
-- and its OK to not turn Java into Scala.  Different languages, different 
philosophies, so its OK if they draw the line in different places.)

Cheers,
-Brian
