About questions you can see into Lua 5.1 Reference Manual \$ (2.5.9 -
Function Definitions)
The statement
local function f () body end
translates to
local f; f = function () body end
not to
local f = function () body end
(This only makes a difference when the body of the function contains
references to f.)

It`s not unnecessary verbiage. It`s release limitation. And may be resolve
in future. I understand  what its "verbiage", so you can use different
keyword?
[self(...)] may be use to normal call in current Lua, [function(...)] in
this context use as function declaration, others?
May be use "verbiage" better?
I sayd what it`s "dark" question, so you not believe :) Go to light :)))

PS: '*'lambda'*' its bold text only from html, and may be you suggestion
better way?
