Handling packages in Go is always something that stops me from going any further when I look at it. Every time I realize I won't be able to properly specify dependencies with versions or pin them (like what Bundler does) it drives me away screaming. It's only the last few years dependency hell has been resolved in other environments (like Ruby and Node, to a lesser and sometimes weirder extent Python), I don't really want to go back in time any more.
