[Python-ideas] Add Standard String Literals and Prefixes for Mathematical Notation

I love regular expressions. I would love to see Bra-Ket notation and many of the popular mathematical forms commonly practiced in engineering and science supported by the Python language in an expressive and logical way. I feel the need for expressing mathematical concepts in a standardized and sightly way, beyond just being able to use Unicode equivalents of mathematical symbols, would be an enormous functional benefit.
