This is a very limited way of thinking about your compiler. It hasn't been mainstream thinking since the advent of Java, which turned "conventional compiler technology" on its head. (Obviously, the ideas quite predate Java, but I'm just speaking of point at which the majority of papers in academic compiler conferences (say, PLDI) suddenly shifted away from purely static compilation.) --scott -- ( http://cscott.net ) _______________________________________________ fonc mailing list [email protected] http://vpri.org/mailman/listinfo/fonc
