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

[Filip Haglund]

New submission from Filip Haglund:

Slicing tuples returns a copy, which is O(n) time. This could be O(1) since 
tuples are immutable, by just pointing to the same data.

This probably applies to other immutable structures as well, such as strings.

Okey, then this is not a bug. I can just handle this special case myself. 
Thanks!
