Lambda Expressions Backported to Java 7, 6 and 5

[Brian Goetz]

Nice work.  It was part of the design process to enable a mechanism like this; it is nice to see this proven and satisfying to see that it was so simple to implement.  

There will in fact be a small change to the metafactory API before GA.
