Certainly not, any symbol can be translated into code or another symbol. A 3D language in a virtual haptic programming environment with dynamic force feedback... that bug is represented by... a bug, your world shakes when the code crashes!
There are bits of library calls I always seem to need to lookup, I'm sure if I found it by reaching way back to the left and twisting, it would always be 'at hand'. I want to dance my code!
Pragmatically tho, the significant convenience of the common denominator of common keyboard symbols trumps most attempts so far.
