That has nothing to do with Init or a Constructor?

That's a fairly standard, boring class reference.

Remember that to reference a module, the module doing the ref must load
_after_ the target.

You can keep that Global, again Init(); has nothing to do with it?

That sounds like a problem with your module.

I don't know.
