[issue12345] Add math.tau

Python will really follow the tau sort joke ? I never saw it mentioned in any serious math or programming document. All the github search result looks like people who are in this joke (kind of).


The page http://tauday.com/state-of-the-tau list very little use of tau in relevant domains, the most relevant to our discussion would be the including of tau in modula-2 standard library.

I don't see how the introduction of the unknown tau constant in python programs will make them clearer or better to the targeted public who will read them.

I must confess however that 2*pi occurs frequently in formula and these formula would be simplified if tau was used. However an honest and non partisan web site would list all the use of pi without 2 where the formula would be more complicated. I don't see that so I'm still not convinced.

I know that Guido van Rossum is the Benevolent dictator for life of python, but as I understand it until this point, the dictator position was used after all argument took place and not before.
