I have scipy 0.9.0 on python 2.6,  2.7 and on 3.2

>>> import scipy
>>> scipy.__version__
'0.9.0'

On 2.6 and 2.7 factorial is still in the scipy. namespace, but not in 3.2

I thought some scipy.misc function where still an exception to the
load the subpackage rule

>>> import sys
>>> sys.version
'2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)]'
>>> import scipy
>>> scipy.__version__
'0.9.0'
>>> set(dir(scipy)) & set(dir(scipy.misc))
set(['info', 'lena', 'comb', 'pade', '__all__', 'Tester', 'factorial',
'factorialk', '__file__', 'who', '__builtins__',
'central_diff_weights', '__package__', '__path__', 'source',
'__name__', 'test', 'derivative', 'factorial2', '__doc__'])
>>>


>>> import sys
>>> sys.version
'3.2 (r32:88445, Feb 20 2011, 21:30:00) [MSC v.1500 64 bit (AMD64)]'
>>> import scipy
>>> scipy.__version__
'0.9.0'
>>> set(dir(scipy)) & set(dir(scipy.misc))
{'__cached__', 'info', '__all__', 'Tester', '__builtins__',
'__file__', 'who', '__package__', '__path__', 'source', 'test',
'__name__', '__doc__'}


I'm fine loading from misc, I was just surprised
