When you read a great novel you almost feel as if your there in your head. When I read you code, I know what the program does, but if its elegant or even brilliant, I have no idea what it was like in your head the day you wrote it and where that epiphany percolated from.

I think a computational language would emphasize how you perceive the program in your head, or at least experience reliably how other people do AND do the thing (unlike state diagrams and flowchars, uml etc)
