Re: Thoughts wanted on automatically "wrapping" existing functions.

Try something like this

local I=setmetatable({},{
        __index= function (t,k)
                        print("def",k)
                        local f=function(...)
                                        print("call",k)
                                        local result=_img[k](_img,...)
                                        show()
                                        return result
                                end
                        rawset(t,k,f)
                        return f
                end
})

I.setpixel(1,2,3,4)
I.setpixel(10,20,30,4)
