Diez,
Thanks, you're right.
Delegated attributes are not in the dir() result.
>>getattr(reg, "pattern")
'[0-9]+'
>>getattr(reg, "flags")
0
>>getattr(reg, "groupindex")

I tried following code in Python shell using a regular expression. Why doesn't the result of dir(reg) have 'pattern', 'flags', and 'groupindex' although they exist as members of _sre.SRE_Pattern instance ?
It sort of irritates me, because whenever I write Python code using a module which I'm not used to using, I often try Python shell with TAB complete to find out the member of module/instance.
It could be that the result overloads the __getattr__-method to delegate
calls to some object. Thus it's not part of the outer instance.

Didn't I read that Py3 will support a __dir__ method so that classes
*could* report such pseudo-attributes in response to dir?

It's already there in 2.6:
.... class X (object):
.... def __init__ (self, a, b):
.... self.a = a
.... self.b = b
.... def __dir__ (self):
.... return ['a', 'b', 'c']
....
>>dir (X (1, 2))
['a', 'b', 'c']
>>>

I don't believe that it possibly could:
class foo(object):
def __getattr__(self, what):
if what[0] == 't':
return True
f = foo()
print f.toby
