I recall at college in 1989 our lecturer had brought in a chap who'd done an entire airline baggage management suite written in prolog (turbo prolog, to be more accurate). The demo we saw was absolutely gorgeous -- real time updates on-screen to changes in baggage locations elsewhere (in the system). This was on i386-equivalent machines, before anyone gets overly nonchalant. He explained that he'd been up against two competing tenders - one in COBOL, the other in C - both higher priced and longer delivery times. Nonetheless, I still never really properly grokked prolog, as much as I tried. I feel my brain had already been wired away from declarative languages. Perhaps a poor cop-out.
