Comment(by klee):
Two cooments:
I don't see natural use cases for total_degree_ungraded() when one use
non-default grading with a polynomial ring. If one need such a method for
(I think) a very rare case, s/he can define it just for the case. The name
is also confusing.
On the other hand, exponent(x) method, which Maarten suggested, would be
useful and essential. Moreover you can make exponent() to return the sum
of all exponents of the variables in the monomial, making
total_degree_ungraded() redundant. Like degree() method, if exponent(x) or
exponent() method is applied for a polynomial rather than a monomial, then
the highest of the values for all monomials may be returned.
