Java makes it awkward and tedious to return multiple results from a method
and something equivalent is needed to return even a single result from a
Runnable. Hence, Callable<T>, etc. Programs do need to do that. There are
plenty of use cases where local variable capture is a reasonable choice,
like SwingUtilities.invokeAndWait or CountDownLatch(1). I'm not sure
attitude helps people deal with this issue, though it has certainly helped
Project Lambda not deal with it. :)
