There are some true ternary operators, like perhaps definite 
integrals. There's probably some true quaternary operators as well, 
so where do you stop? Binary just happens to be a useful place to 
stop. You could even have one or zero places, but this would turn 
out to be very wordy in a spoken language. Might be worth 
investigating in a numerical language though.
