On can use the big-oh notation


when x is a generator of a power series or a laurent series. It is convenient to also be able to use this notation when the parent of x is another ring (for example, a subclass of a power series ring).

For this, we only need x to implement and x.add_bigoh(). I made a patch for sage.rings.big_oh that tests for this and returns x.add_bigoh( when possible.
