Fixed a 'long-running' bug with regard to parent-method detection. Apparently I was sending in a 'BoolObject' from 'HandleInstruction' to the main call-backs, even though that was supposed to be local to that method and its overloads. In other words, if you've been using this as a base-class, make sure you're not pulling what I did. I have also added 'EmitError' for handling this kind of thing. This is more straight-forward, if you ask me. Anyway, this should fix the issue.
