	Maybe I've missed something, but why don't you just:

return {
	simple = require"simple",
	multi = require 'multi',
	shared1 = require 'shared1',
	shared2 = require 'shared2',
	reference = require 'reference',
}

	Of course you'll end up with a hierarchical structure, which
couldn't be what you want.  But I am sure it is worth it!
