I think it would be very useful to improve notation for programming languages as well (we could borrow a lot from mathematics). With all the advances in display technology and unicode everywhere, you'd say there is no longer a need to limit ourselves to flat 7-bit ASCII in a simple grid. Still, we do. Is it really the best way, as it seems lacking on all the above points, or simply a matter of habit?
