Yes; after further thought, I agree having tau = 2.0*pi is preferable.

Kinda reads like it's taking a stand on which of the two is the *real*
fundamental mathematical constant and which one is a hack. Therefore it
should really be pi that's set to tau/2.0 :-)

Can PI have a @see link to this so that people know about it?

(I'll just mention that {from,to}Radians would also benefit from some
advertisement, as a great many PI usages are dividing it by or into 180,
but do what thou wilt with that FYI.)
