So, in other words, to achieve this from C-side:

1. I must create a table.
2. Assign it a metatable with the __call metamethod.
3. This __call method will perform the module init.

But, what if I don't pass any parameter to require? 
Will it call metamethod __call ?

I want to be able to do both:

  require 'canvas' -- assumes, '/dev/fb0'


  require 'canvas' '/dev/fb1' -- changes, default behavior
