One of the biggest issues I have with the current AST is that I don't believe it really gets the "slice" and "extended slice" terminology correct (it uses 'extended slice' to refer to multi-dimensional indexing, but the normal meaning of that phrase is to refer to the use of a step argument for a slice [1]) The two were introduced together and were referred to together as "extended slicing" at the time, so I'm not sure who is confused.

Ah, that would explain it then - I first encountered the phrase 'extended slicing' in the context of the Python 2.3 additions to the builtin types, so I didn't realise it referred to all getitem based non-mapping lookups, rather than just the start:stop:step form of slicing.

Given that additional bit of history, I don't think changing the name of the AST node is worth the hassle - I'll just have to recalibrate my brain :)

Cheers, Nick.
