Feedback and comments on ARM proposal

[Tim Peierls]

How about using a special package -- java.lang.auto, say -- with initially
only one or two interfaces -- AutoCloseable and AutoDisposable, say -- and
word the ARM proposal so that only subtypes of interfaces with a single,
parameterless method that are declared in this special package are allowed
in the ARM try-initialization?

The idea here is to remove the decision about which clean-up methods to
support from the current proposal and make it a library design issue.
