    214214  "Return an expression which will efficiently adds/subtracts two
    215215polynomials, P and Q.  The addition/subtraction of coefficients is
    216 performed by calling ADD/SUBTRACT-METHOD-NAME.  If UMINUS-METHOD-NAME
    217 is supplied, it is used to negate the coefficients of Q which do not
    218 have a corresponding coefficient in P. The code implements an
    219 efficient algorithm to add two polynomials represented as sorted lists
    220 of terms. The code destroys both arguments, reusing the terms to build
    221 the result."
