Re: Module finalization (along the lines of calling a function on exit)

Salve.

__gc function is expected to be part of object's metatable, not the part 
of the object itself.
So you should for example create table with your sole __gc function, and 
set it as metatable for your module (module is just a table? am i right? 
i am not familiar with packaging proposal, nor with compat library).
