> It seems that it might be cleaner at some point to refactor GenerationInfo, so that rather than being a class representing a single value & having a Vector of them, to instead have GenerationInfo be a container holding info for N variables, and make all methods be passed the virtual register to be operated on.  Then the generation info could hold a reference to m_stream as a member, which would better encapsulate the implementation.
