[issue29506] Incorrect documentation for the copy module

[Steven D'Aprano]

Steven D'Aprano added the comment:

What about "administrative data structures" that should be copied?

I think that "administrative data structures" is a red herring: there could be data that needs copying, and data that needs sharing and shouldn't be copied, independent of what the data is used for.

"Because deepcopy copies everything it may copy too much, such as data which is intended to be shared between copies."
