I'm getting that picture from Raoul. However if it's so easy, why is 
Raoul developing indexing_suite?

Not really as it can't be extended in length. So while it looks like 
a list and acts like a list, it's not a list.

(Don't worry, the users will know this. And remember this affects 
about seven different areas of the library which I've never used so 
basically I'm providing a default action for users so they can tell 
me afterwards if they don't like it).
