Harry Pierson, Program Manager of IronPython, ran this year’s Lang.NET Symposium held on Microsoft's campus (make sure you watch the talks, which are available for your viewing pleasure). We were of course there and conducted several interviews with some of programming language design's brightest thinkers. Here, Harry shares with us the thinking behind Lang.NET. Thanks to Harry for inviting Channel 9 to the venue and providing us with a room to conduct interviews! See all the C9 Lang.NET conversations here. There numbers will grow over the coming week so check back.
