Summary: copy() method of dictionaries is not "deep"

Initial Comment:
Unlike copy.deepcopy() the copy() method of a 
dictionary does not copy objects in the dict, but 
seem to use them by reference.

I'm not sure, if this is really a bug - but I would 
have expected it to behave like copy.deepcopy(), 
according to 
http://www.python.org/infogami-faq/programming/how-do-i-copy-an-object-in-python/

Sorry, I can't since I don't have any privileges there too.
Assigning to AMK, perhaps he can do something about it.

I cannot comment on infogami. It says the following is 
spam:
"""
Please note that olddict.copy() does not "deepcopy" the 
dictionary.
So if you have a dictionary of objects, those will still 
be copied by reference.
"""

I've tried rephrasing it slightly, to no avail. Can you 
update the wiki page directly?

Thanks.

So it's not a bug?

Then please change the "Resolution" accordingly.

The infogami FAQ is "interactive", so if you find the text
misleading, please add a comment yourself via the "add
comment" link. (You may have to login to infogami to do that.)
