I don't want to be rude -- is English your first language? -- but I
found this article to be written in particularly baroque prose. I'm
not quite sure what your central point is.

Well, I dunno. If it was my decision, there's no way it would be
mentioned in the builtins.

No changes here in a long while.

I don't think it's unreasonable at all. To me the copy module is
something you only need when you really need it, then you go looking
for it.

Certainly, the failure to understand assignment and erroneous beliefs
that the copy module is necessary in a given situation go hand in hand.
Assignment in Python *isn't* particularly subtle, though. My
impression is that it's people from e.g. C who get tripped up here,
not total newbies.

Another reason might just be that copy() is implemented in Python...

Have you ever used the copy module? I am *not* a beginner, and have
used it *once* (and I can't remember what for, either).
