Goshim: Building a Better Go Dependency Management Tool

Go dependency management is essentially non-existent; this is known. It is also a source of frustration for many in the Go community. The standard Go tools are generally awesome, but the closest thing to dependency management Go provides out of the box is that go get will prefer VCS tags corresponding to the current go version. Afaik, nobody respects (or is even aware of) this convention. This is not entirely surprising, as Rob Pike himself has said that depedency management is a problem left for the community to solve. In fact, the reason why import statements are constructed with a string argument is to allow future support for arbitrary syntactic choices in specifying dependencies. I suspect that when the compiler is fully rewritten in Go, the community will jump at the chance to submit pull requests that support package versioning. Until then, we must build tools to help us strictly define our depe
