Go's users and designers make all sorts of claims about it. As it happens, I've evaluated them and find that I often disagree with them.

For instance, Go projects often don't specify the versions of their dependencies and choose to just clone the code into their own source tree instead - if you're lucky. If you aren't then the project simply depends on whatever is found in the dependencies git master branch. I find this to be poor practice from several perspectives, maintainability amongst them.
