If even 50% of this makes it into C# it's going to be a pretty amazing language.

Native code interfaces were already reasonably fast, allowing more no copy semantics and array slice behaviour is going to do wonders for native library performance.

I really hope they implement this. It would make IO so much more efficient if you could pin a big chunk of memory and allocate buffers from it.
