Hmmm... right... you are trading one set of problems for another, e.g.:

% cat TestFoo.lua
module( ..., package.seeall )

print( _NAME )

% cat TestBar.lua
module( ..., package.seeall )

print( _NAME )

% cat TestBaz.lua
print( require( 'TestBar' )._NAME )
print( require( 'TestFoo' )._NAME )

% lua TestBaz.lua
TestBar
TestBar
TestFoo
TestFoo

% luac -o TestBaz.luac TestFoo.lua TestBar.lua

% lua TestBaz.luac
lua: TestFoo.lua:1: bad argument #1 to 'module' (string expected, got  
nil)
stack traceback:
	[C]: in function 'module'
	TestFoo.lua:1: in main chunk
	(luac): in main chunk
	[C]: ?

Ooooops... your code now depends on its physical representation... oh,  
well...
