Here it is: *3.3.2.1. Customizing module attribute access*

Oh! That's brand new in 3.7, no wonder I didn't know about it.
I did see the core developers talking about adding this feature, but I
didn't know that they had done so.
Your original question was:
In the simple code like what are the advantages we get from? Is this
so that we can implement more special methods than just __getattr__
and __dir__ in the module level?
Yes, that's what the documentation says. I don't see any reason not to
believe it.
Well I believed it, but I was not sure if I understood it correctly. So
I was trying to confirm myself by those who understand the language.
BTW, one thing I would like to know about this list is that, everytime I
send an email I see it the in list after 2 hours approx. Is this for me
or everybody? I am just curious.
Oh, this is cool! I'm going to enjoy playing with this...
py> from types import ModuleType
py> class Magic(ModuleType):
... count = 0
... @property
... def spam(self):
... self.count += 1
... return ' '.join(['spam']*self.count)
...
py> import sys
py> sys.modules['__main__'].__class__ = Magic
py> import __main__
py> __main__.spam
'spam'
py> __main__.spam
'spam spam'
py> __main__.spam
'spam spam spam'

Thanks,
