Perhaps it bothers the programmer with something that shouldn't bother him. I mean that I might do help(set.copy), and then think, "Oh, it returns a shallow copy. Wait a minute - 'shallow' means that I get a new object, which references the same objects as the old one. Perhaps I should use another function, which does deep copying? Let me think about it - no. All members of a set are immutable, so it doesn't matter." I think that in this case, the fact that the copy is shallow is an implementation detail, since there's no sense in making a deep copy of a set. Implementation details should probably not be a part of the definition of what a method does. I know it's just a word, and that it doesn't matter a lot. But why not make things a tiny bit better?
