For reasons that don't really matter, I need to have a vocabulary named hello-world and I need to be able to run its tests, and I need it to shadow the hello-world from Factor's standard library.
I have not been able to do this successfully (I tried reversing vocab-roots but it did not make a difference). Is it possible?
