I've tried Go some too. I disagree with your assessment of the data structures (inheritance isn't always great), but the tool thing I strongly agree with.

I'd note that all the replies at this time argue the point about data structures, but none address the tooling.

I want my autocompletetion, dammit! And I don't want to use Emacs or Vi to get it.

The lack of refactoring support was what ended up making me switch back to Java+Dropwizard. I'm just much quicker at evolving services because of the better tooling.
