I propose to reverse the order of polynomial coefficients used by polyval
etc. It was changed to the present order for compatibility with Matlab and
SciPy, but I find this convention annoying every time I use it.

First, the Matlab absolutely makes no sense when working with polynomials
as truncations of power series. Second, having entry i be the coefficient
of x^i and nothing else is just more convenient and less error-prone.
