With its well defined AST, I think Go can "easily" accommodate optimizations as described, but obviously at the expense of compililation time. And I gotta tell you that keeping compile times down is the more important optimization for me. However, I happily add automated scans for safety and correctness into my release candidates, and I would gladly pay for optimizations at that point. As long as I can test rapidly with the knowledge that I can add an "-O3" flag just before release would be a perfect compromise for me.
