ranked code size creating a lambda counter, incrementing once, and assigning result to a local

mylang.txt

I'm not saying terseness is an inherent virtue, I'm just saying it be like it is.

-- Lua
local counter_once = (function() local x = 41; return function() x = x + 1; return x; end end)()()

// Old JavaScript
var counterOnce = (function () { var x = 41; return (function () { x++; return x; })})()()

;; Emacs Lisp
(let ((counter-once (funcall (lexical-let ((x 41)) (lambda () (setq x (1+ x)) x))))))

// C#
var counterOnce = new Func<Func<int>>(() => { var x = 41; return (() => ++x);})()();

// C++14
auto counterOnce = []() {auto x = 41; return [&x]() { ++x; return x; };}()();

;; Racket Scheme
(let [(counter-once ((let [(x 41)] (lambda () (set! x (+ 1 x)) x))))])

// Modern Javascript
let counterOnce = (() => { let x = 41; return (() => ++x)})()()

// MichaelScript
let counter_once = fn () { let x = 41; fn() do x += 1 }()()
