I lost a couple of hours this morning because I was importing github.com/src-d/go-kallax instead of gopkg.in/src-d/go-kallax.v1. Everything seemed to work (I vendored using dep) except I would always end up with a blank template for the kallax.go file. This isn't a super actionable issue other than maybe a stronger docs callout but I wanted to at least file an issue incase anyone else ran into the same problem.
