"or" question

[Ando Sonenblick <ando@...>]

Gang, I looked at an implementation of a method that I have in my  app:

	__index = function(object, key)
			local result = SpriteMethods[key] or
				AnimationMethods[key]
				
			if result == nil then
				result = (ObjectTables[SSGetUserDataObjectPtr(object)] or {})[key]
				if result == nil then
					result = IdentityMethods[key] or
						ObjectMethods[key] or
						AdvanceableSpriteMethods[key]
				end
			end
			
			return result
		end,


Once I saw it again (I wrote it quite some time ago) I thought, isn't 
that equivalent to:

	__index = function(object, key)
			return SpriteMethods[key] or
				AnimationMethods[key] or
				(ObjectTables[SSGetUserDataObjectPtr(object)] or {})[key] or
				IdentityMethods[key] or
				ObjectMethods[key] or
				AdvanceableSpriteMethods[key]
		end,

Since I've been concentrating on the non lua parts of my app for a 
while now, I just wanted to double check that the two versions of the 
method are indeed equivalent...

thx,
ando
