This is quite a respectable approach in the dynamic universe!

But, yes, there's a better way; ask the modules to export an object
factory (if that fails then it's definitely bad) and insist that these
objects all have a metatable which contains some distinct field/value.
 This field can then identify the interface; the value can be made as
distinct as you like.
