In the .NET bytecode specification (called "CIL", Common Intermediate Language), there is the possibility to define something as "volatile", and... guess what? it is accesses that can be marked so, not variables!

This reinforces my idea that the .NET standard is very well thought out: they really learned from the mistakes of the past, at least on technical issues.

You're implying that "volatile" in C was a mistake. It wasn't. While it isn't useful for coordinating threads on separate processors in a 2007 Linux kernel, it's just fine for what it was designed for: coordinating a CPU with a memory-mapped I/O device in the early '80s.

I don't know anything about .NET, but I think the most you can conclude from this volatile thing is that .NET is designed for more modern computers than ANSI C. And that the spec is written poorly -- "volatile" is the wrong word for this.
