let's play TDD, tackles closures in java

[Neal Gafter]

Brian-

The Oracle documentation for Java SE 7 currently teaches this
technique<http://download.oracle.com/javase/7/docs/technotes/guides/security/doprivileged.html>,
but the code there could more cleanly use the generic versions of
doPrivileged.

Perhaps it would be helpful if you would describe the preferred way to write
sequential code where part of a local computation is performed inside a
lambda (but where the part performed inside the lambda is more complex than
just returning a single value).  Do you believe that such computations
should be done using variables hand-hoisted to fields of some class (perhaps
one built just for that purpose)?
