Lua vararg iteration benchmark
This small benchmark test compares the performance of using `ipairs{...}` vs.
`select('#',<n>)` to iterate over the arguments inside a variadic function.

Proof of concept of hijacking individual keys directly in an object and assigning them change callbacks
values = Symbol("values")
hijack = (object, callbacks) => {
const val = object[values] ||= Object.create(null)
Object.entries(callbacks).forEach(([key, callback]) => {
Object.defineProperty(object, key, {
get() { return val[key] },
set(value) {
callback(value)
val[key] = value
return true

Thoughs on how to implement 2D collision handling

Polygon-Polygon collision

let A and B be polygons

let a and b be vectors representing the movement of said polygons within a game tick

let c be the movement of A relative to B a-b

calculate the transformation matrix Ta that transforms c into the vector (1, 0)
