I'm actually a huge fan of Rust's memory model and wished Go had something similar, since it's faster to use smart pointers, and less calls to the garbage collector are required. I also love how rust uses three different kinds of pointers depending on how the memory is managed, and although it adds some complexity, it gives more semantic value to the data you are working with.

Unfortunately for me, the rust compiler is written in rust, so I would have to adventure to grab a Linux and try my hand at a cross compile before I can play with it on my OpenBSD box.
