Comment #3 on issue 2393 by [email protected]: Sum error
http://code.google.com/p/sympy/issues/detail?id=2393
Because k.is_Integer is equivalent to isinstance(k, Integer), e.g.:
In [1]: var('k', integer=True)
Out[1]: k
In [2]: k.is_Integer # like isinstance
Out[2]: False
In [3]: k.is_integer # uses 'integer' assumption
Out[3]: True
