custom __type metamethod

Questions
1

I want to make a metamethod in order to, for example, the type(Vector2(0,0)) was “Vector2D”, not “table”. To do this, I rewrote the type function from Lua

local _type = type function type(v) local T = _type(v) if T == "table" then local tf = getmetatable(v).__type if _type(tf) == "function" then return tf(v) else return tostring(tf or T) end else return T end end

But when I run the project, Codea crashes every time (the Problem disappears if i rewrite the type function inside the setup function). Why? How to fix this?

Okay, I see what the problem is. I haven’t checked whether the table has metatable. Now everything works as it should
rawtype = type function type(v) local T = rawtype(v) if T == "table" then local mt = getmetatable(v) if mt then --fix if rawtype(mt.__type) == "function" then return mt.__type(v) elseif rawtype(mt.__type) == "string" then return mt.__type end end end return T end
