If I were designing a language from scratch today, with full Unicode support from the beginning, I would support a rich set of operators possibly even including MIDDLE DOT and × MULTIPLICATION SIGN, and leave it up to the user to use them wisely or not at all. But I don't think it would be appropriate for Python to add them, at least not before Python 4: too much effort for too little gain. Maybe in another ten years people will be less resistant to Unicode operators.
Python has cleverly left the $ symbol unused. We can use it as a quasiquote to embed executable TeX. for x in xrange($b \cdot \sum_{i=1}^n \frac{x^n}{n!}$): ... No need to wait for that new language, we can have a rich set of math operators today! -- Devin
