It's worth remembering that Lua (and the current implementation) doesn't 
actually guarantee two identical holey tables will have the same length.
So comparing lengths isn't a good shortcut unfortunately..

As an example running this on Lua 5.1:

local t1 = {1, 2, nil, 4, nil}
local t2 = {1, 2}
t2[4] = 4
print(#t1..", "..#t2)

will print: 2, 4
