[issue9021] no copy.copy problem description

[anatoly techtonik]

New submission from anatoly techtonik <techtonik at gmail.com>:

`copy` module covers very important aspect of Python programming. However its documentation doesn't provide any intro or overview of this problem starting right from details. When people meet `copy` construction in the code - the refer to module documentation and its doesn't completely answer two basic questions they have:

1. why copy module is needed (i.e. what's the problem with var assignment)
2. when and where it should be used
