Alright. I'll comment. -- I find it interesting to learn just how much the Go compiler can "optimize your code away". That's both good and bad.<p>The point on benchmarking the right thing is 100% spot on, same goes for testing too. The optimization problem however is a bit too contrived IMO. When would you possible write code (aside from very trivial things) where the compiler would optimize all your code away, thus making your benchmarking invalid? I want to see a real-world example of where someone has been caught out by this?
