I purged my own hysterical rant.
To sum it up: the root problem is circular instantiation.
GP1 is generic, wants numerical type and operations.
GP1.G_Child needs P2, P2.Child and P2.G_Child, and P2.G_Child needs as pack=
age parameter GP1. I say needs as in "functionnaly", so instead of requirin=
g a package generic parameter, I could stick with having the numerical sign=
ature outside, instantiate it, and instantiate GP1 with it.
But I'm not sure this is a way out.
Originally, none of these were generics, so these problems weren't happenin=
g, I think.
