Yeah, it's widespread as a hand-coded thing. It has to be - you essentially have no choice in Go for even basic things like tests.

But that just means that everyone rolls their own thing by hand, with widely-varying feature-sets, method names, bugs, etc. DI frameworks are very much nicer for interop between a bunch of libs.
