The last thing I'm curious about is compilation time, especially since that's taken a hit or two recently. I know it's easily a net win with numbers like that, but one of my favorite parts of Go is the quick build times, and thus quick iteration times.
Also, since Go is self-compiled, does that mean we'll have to wait until 1.7.1 for the speed improvements to hit the compiler? :-P
