Depending on the engine property it can be changed before each compilation. So the ones that are only affecting how the compiler behaves can definitely be per module.

Now that I'm sitting in front of my computer I could review your code better.

As far as I can tell, the class my_int should be registered with the following flags: asOBJ_VALUE | asGetTypeTraits<my_int>() | asOBJ_APP_CLASS_ALLINTS.
