(估計 #2501 是 duplicate)
我在搜 overload 相關 issue 時找到這個

@overload fun() 目前仍是不支援 generic 的，#2484 增加的 capture 寫法是針對 @param
目前我試出 workaround 是額外寫1段 不會執行的 if 代碼，單純用來 騙 luals 🤔

---@class frame
local frame = {}

---@class frame.button

local newframe = setmetatable({}, {
    __index = frame,
    __call = function (self, name)
        local class = rawget(self, name)
        if class and getmetatable(class) then
            return function(param)
                return frame(class, param)
            end
        end
    end,
})

if false then
    ---@generic T
    ---@param name frame.`T`
    ---@return fun(param: table): T
    ---@diagnostic disable-next-line
    newframe = function (name) end
end

local a = newframe 'button' {
}

• 這樣能將帶 generic 的 function type union 到 newframe variable 之中
