[issue26077] Make slicing of immutable structures return a view instead of a copy

[Marc-Andre Lemburg]

Marc-Andre Lemburg added the comment:

While it's theoretically possible, there's a reason why we haven't done this in the past: we don't want to keep the possibly large original object alive when using a slice.

For buffer interface types, you can already use memoryview to get a view in case you need this.

In most other cases, it's better to work with indexes into the original object rather than views on the data.
