Updated State of the Lambda

[Brian Goetz]

> The argument of not referring to 'this' as the lambda uses a argument to say that a lambda that doesn't hold onto the enclosing class' instance will be more memory efficient than one that does (c.f. inner classes).

No, it does not.  This is not part of the argument for or against, this is simply an observation about a desirable characteristic.  The decision was made before making this particular observation.  Inner classes could potentially also acquire this characteristic, as you point out, though compatibility becomes more of an issue with that (and it is not currently under consideration.)
