Comment:
Two comments:
- For every bug fixed, there needs to be a doctest showing that the bug
has been fixed.
- It is not clear to me that this is the correct fix; I would find it more
appropriate to change the method `LaurentSeries.power_series()` to raise a
`ValueError` instead of an `ArithmeticError` when given a Laurent series
containing terms with negative exponents. (It seems to me that
`ArithmeticError` is intended rather for things like zero division and
overflow.)
