<shrug> Either option would cause someone to complain. It's not a
cut-and-dry issue. However, since strings can be atomic elements
through the various '|S<N>' dtypes, and we already have rules to
special-case strings as atomic, "numpy.isscalar('string') == False"
would be more inconsistent.

In [1]: from numpy import *

In [2]: array(['one', 'two'])
Out[2]:
array(['one', 'two'],
      dtype='|S3')
