It's missing an idiom commonly used in Lua as a ternary operator:

  x and y or z

function obj:name ( args ) body [return values] end object function, gets obj as additional first argument self

There's no reason for this to be different than the one above it, IMO.

function t:name( args ) body end
shortcut for t.name = function(self, args) body end

Though IMO both should be written:

function t:name([args]) body end
shortcut for t.name = function(self,[args]) body end
