I too use Scala and Go professionally and agree with all of your points, but I want to add one. Code reuse. I am tired of copy/pasting, rewriting the same things, forcing my same-lib packages to be unidirectionally dependent, etc. I've often contemplated what could happen if Go had syntax-extension macros that could build new AST (not go generate, and not in the same language). I believe that Go may in turn become a quality target for a better language. Not oden which didn't have any corporate backing, and from my experiences it doesn't compile fast enough or have quality enough DCE to support reasonable JVM cross compile.
