I would also appreciate != instead of ~=. Not only because I'm more used to it, but also because everytime I want to type '~' I have to press the '~' key and then the spacebar (that is, two keypresses instead of one). That's the default Windows "USA International" keyboard layout, which I believe is widely used.

The "new" != operator could be introduced in Lua 5.x (5.1?), and later on (maybe in Lua 6.0) the ~= operator could be dropped.
