I've never really felt the need for them. When I need that kind of behaviour 
file-wise, I use something like

local MY_CONSTANT = 10
-- ...
for i = 1, MY_CONSTANT do
 --..., etc
end

If I need module-wide (and exported) constants, I place them inside my "class" 
table, thus:

MyClass = {}

MyClass.HELLO_MSG = "Hello!\n"

function MyClass:print_msg( message )
	print( 'MyClass says, "'..message..'".' )
end
----- 8< --- another module ---- 8< ----
MyClass:print_msg( MyClass.HELLO_MSG )

...or something to that effect.

Hope that helps,

Cheers,

	Pedro.
