How to avoid bounds checking?

@huon

This already exists in the form of Iterator (for sequential access)

Right, but it's not general enough.

@huon

and, more generally, via tricks such as @bluss's indexing

I think no one is using that... And I think the things I'm talking about need to be built-in. I'll discuss this topic in another specific thread when I'll know Rust better.
