Here is a new video on Channel 9 where Anders Hejlsberg from 36:30 in the interview starts talking about immutability in C#. He gives a very good use case for popsicle immutability and explains how this is something you are currently required to implement yourself. It was music to my ears hearing him say it is worth thinking about better support for creating immutable object graphs in future versions of C#
