"Modules in a layer do not depend on other modules in the same layer. "
Yes, that is the strict convention. However, I am no longer sure
if that's strictly followed. When designing architectures like Spirit,
I take it to task to do extensive analysis (create dependency graphs,
etc.). However, typically, commits after commits somehow disrupt the
convention, so I am no longer enirely sure if the strict adherence
to the design still holds.
