callers can decrease the degree of a polynomial
True. This was intentional. The reason for this is that we want to have constant time operations on polynomials. Therefore, the function degree
and its usage was removed and replaced with size
. In general, the crate has no idea what a degree is.

not a bug, but an oddity. the API allows callers to change the coefficients of a polynomial, but not to increase its degree. callers can decrease the degree of a polynomial by setting higher degree coefficients to zero.
