My understanding is that a few of those example are now incorrect/obsolete:
String Index: as per @expede, indexing on strings is now disallowed, to match jq
Optional Iterator, .[][]?: the spec says that iterator on arrays are no-op. It makes sense imho, as jq output multiple values with that, which we can't.
Nested Iterator, .[][]: same reason
- slicing is start:end, not start:length, but importantly start to *excluded* end
- backward slicing is illegal
- slicing on string is allowed
- slicing on strings operates on runes, not bytes
- removed field selection against a list
- a selector return exactly one node, or nil
- implemented the full set of slicing, including negative indexes
- plenty of other cleanup and simplification
