What for? You are not accessing the userdata's memory directly from Lua 
so you don't *need* the actual userdata type for type safety, and if you 
check for it anyway you run into the same issues as with 
function/is_callable, i.e. you lose the ability to pass e.g. a mock 
object instead of the real thing (or an object "writing" to an array 
instead of a real file object) ...
