It would be nice if the error message for an AttributeError could include the module name when getting from a module -- just like it does for getting from a class.

This would make the message more helpful.  For example, it would help in diagnosing issues like the ones mentioned in this report:

http://bugs.python.org/issue7559

EXAMPLE (using latest from trunk Python 2.7a4+):

import sys

class TestClass(object):
    pass

m = sys
c = TestClass

print "CLASS: %s" % c

try:
    c.asdf
except AttributeError, err:
    print err

print "\nMODULE: %s" % m

try:
    m.adsf
except AttributeError, err:
    print err

***
OUTPUT:

CLASS: <class '__main__.TestClass'>
type object 'TestClass' has no attribute 'asdf'

MODULE: <module 'sys' (built-in)>
'module' object has no attribute 'adsf'

***
The latter message could instead be (paralleling the text in the case of a class)--

module object 'sys' has no attribute 'adsf'
