value, they do not have names. " at a deeper level?

in Lua, functions are values.

so you can do this:

function aFn(a, b)

   return a + b

end

and do this

b = aFn

then

b(2,3) -- returns 5

and also

c = {b}

c[1](3,4) -- returns 7

or this

d = function()

       return aFn

    end ()

d(5,6) -- returns 11

Functions are just values, and a module, any Lua program, is just a function as well.

Hope that helps,
