I think making this work as a template would be kind of tough, actually, if you think about the details (e.g., PLUS_EXPR vs. PLUS vs. GS_PLUS_EXPR). Doable but rather awkward. I guess you could use dozens of template parameters, most of them integers providing the code values. Virtual functions and a table of operator codes would probably work just as well, and be slightly more comprehensible. Ian
