Eclipse plugin+hack to visually collapse (fold) anonymous inner classes to concise lambda expressions (closures) in Java Editor.

Author believe that main problem of anonymous inner classes is not their a somewhat limited semantic (yeah, they aren't real full blown closures!) but verbosity of declaration. While it is not difficult to write anonymous inner classes using completion and/or templates in java editor, reading of such structures can be really hurting.
