I'm going to be "that guy": -- These are the same: -- ...snip... local function g(x) return math.sin(x) end local g = function (x) return math.sin(x) end According to the Lua Reference Manual [1], this example isn't correct. Rather, this is the correct translation: local function g(x) return math.sin(x) end local g; g = function (x) return math.sin(x) end From the manual: "This only makes a difference when the body of the function contains references to f."
