Yeah, I watched it. He advocates:

* pure functions

* local functions

* local functions with the same syntax as global functions

* safety which defaults to off

All of which D does right now.

The only interesting thing is he describes a way that functions (and blocks) can 
specify what global data they access, and then have the compiler issue errors 
for accessing any other global data. He has a way to do that both locally and 
transitively.

However, the same effect can be achieved via pure annotations and passing the 
globals needed by reference as function parameters.

Based on his talks about what he wants in a language, I infer he's not looked at 
D beyond "D has a GC, can't use it".

Another thing I found interesting is I had assumed he'd given these talks at a 
conference. Not so. He simply set up a webcam in his office. It's a great method 
- we should look into doing that.
