Was it Motif, or some other UI system back in the day over-using this technique... There was time when I thought it was good idea, but rejected it for other reasons - no easy way to pass-through arguments (unless you've provided for va_list function beforehand, or use some trampoline hacks). But then the overall safeness... yet people to this day (me included) use "printf" - it's like beer & cigaretes - it's bad, but comfortable, and sexy :)
