Thank you for the hint. 

In defmodule, can one use :includes with multiple other modules?
IOW have modules a single inheritance hierarchy? The manual entry
for defmodule seem to suggest that.

But when I tried, it looked like a module had only one parent. Or
maybe I made a mistake while declaring the modules.

Anyway, thank you.
