Hmm... you can't set tags on variables.  Only on tables and userdata objects.
So I guess you mean that.  Yes, they will be collected.  The gc tag allows
you to set callback functions for userdata objects.  It's just a function
that gets called just before the object is freed.  And the object will be
freed when it's no longer used, whether you set a gc-function or not ;-)
