Hi Brian, Gavin, people,

Thanks for your comments on the idea of List<int> specializing from
List<Any>.

My attention was drawn to the simpler of Gavin's proposals -- 'Any'
implements as Object, but can be specialized. (Second 'tagged union'
proposal I feel would be too complex.)

I know our focus in this current phase is on "Layers", but would like to
educate myself further about the general background of issues with Any. To
this end I have so far investigated the following videos & resources:

- Paul Phillips, Scala War Stories
    http://medianetwork.oracle.com/video/player/2623635250001

- Brian Goetz - Stewardship: the Sobering Parts
    https://www.youtube.com/watch?v=2y5Pv4yN0b0

Brian, I did want to research the JVMLS 2014 keynote you mentioned;  is
that you with John Rose "Evolving the JVM"?

- John Rose & Brian Goetz, Evolving the JVM
    http://medianetwork.oracle.com/video/player/3730888982001

Let me know if this is the video you referred to, and if there were any
other good resources?

As an aside, I was very interested in the "Stewardship" video, and
appreciated the important perspectives Brian conveys & is responsible
for... I also got a little bit more insight into Brian's concern with
serialization!

All the above videos very informative & recommended.


Regards,
Thomas Whitmore
