The buffer interface was designed for the slice-as-copy use case:

This answers my musing about shared slices. But it points me at another
question: why is buffer() listed in "Non-essential Built-in Functions"?
While it is obviously not essential like str() or list(), it isn't
deprecated like apply(). On the other hand, some other built-in functions
listed under "Built-in Functions" are probably also not essential (I'm not
going to go any further out on the limb by giving an example!).
Perhaps I misunderstand the intent of this manual page.
