Template instantiation

[Trass3r]

Got the following code:

public LuaState wrapClass (T) (T instance)
{
	auto ptr = cast (T *) newUserdata ( (T *).sizeof);
	*ptr = instance;

	loadClassMetatable (typeid(T).toString);
	setMetatable (-2);
	return this;
}

Am I right in assuming that a different wrapClass will be created in the 
final executable for each template instantiation (e.g. calls with class 
A,B,C,... instances) and would thus bloat up the executable a bit when 
used with many classes?

Apart from that, couldn't you just use wrapClass (Object instance)? In 
the end each class instance pointer takes up the same amount of memory?!
