I know some functional languages (and Algol 68?) do this, when they can -- just stack up Things To Do until an output or a decision is required, then figure out just what is needed to generate or make the output/decision. How would this work in perl? We'd have to stop relying on side effects and well defined short-circuiting, for one -- or would we?Thread Previous | Thread Next
