Does Go have versioned libs yet? Last time I tried it, people were asking me to compile something that depended on another git repo, like a direct connection to a different git repo, that had diverged in API. And it was broken - no one cared, almost like that's normal. This was probably 10 years ago though, so it's probably different now.

Self answered - Go Modules. I guess so. I'll take another look, getting sick of Python lately.
