Explicit Bin - requires you to pass functions or method names

Bin.lua

--- Creates a new bin object for cleanup.

	-- Adds an item to the bin.
	local function add(item: () -> () | { [any]: any } | Instance | RBXScriptConnection, cleanupMethodKey: any?)

Example:

local food = { eat = function() end }
local object = { Destroy = function() end }
local connection = Instance.new("BindableEvent").Event:Connect(function() end)
local part = Instance.new("Part"))
local someCleanupFunction = function() end

binAdd(food, "eat")
binAdd(object, "Destroy")
binAdd(connection, "Disconnect")
binAdd(part, "Destroy")
binAdd(someCleanupFunction)
