The other nicety that goes hand in hand with this is crazy simple cross compiling. My current project uses cgo and pcap so I don't get to use it now [1], but my last and next project allow me to hit a single command and have nice statically compiled binaries for FreeBSD, OS X, Linux and Windows in a very small amount of time with almost no setup effort.

I still need to get it wired up to the GitHub API for downloads and life will be perfect. I can push to master and upload a build for download all in one fell swoop.

([1], cross compiling is not [currently?] supported with cgo)
