Re: luabind - problem with luabind::object reference

Yes, the object has a reference. However, the object should releases the 
reference when it is destroyed. Which happens immediately after creation.

No, his problem is the fact that the object is /still/ on the stack. 
Luabind's from_stack call does /not/ pop it off of the stack for you; 
you have to do that yourself.
