Hi @tkf, I hear you, and that’s exactly what I tried, but it doesn’t really work. See "Unsatisfiable requirements" when local packages use local packages (fixed in v1.4).
(It may work in v1.4; I haven’t verified yet.)
I attribute the fact that it doesn’t work to the fact that “local packages” like this are not first class citizens, and ]dev is meant as a short-term thing, not something you build your program on.
