[erlang-questions] Parameterized module initialization

There is no point in trying to enforce that with the current implementation, you're right; but what I would like is proper functors where BEAM knows about them and not just modules transformed at compile-time. A man can always dream, right?

The implementation is not simplified - it gets more complicated. In practice, it is probably a good idea to mostly parameterize modules with respect to other modules (i.e., callbacks), but there's no point in trying to enforce that.
