- Simplify group_indices - Only for C ordered, remove complex compile time. - Could be generalized to non C ordered, but no need. - Fix slice for custom orders. - Generalize the group_indices for the custom order. - Add c_ordered_transposed_view (useful ?) - Improve slice, special for ellipsis (quicker). - Simplify TraversalOrder - Assignement. Specialize one case for speed. - use FORCEINLINE in foreach, according to speed test for clang - add one speed test - Modify iterators for better speed. - along the lines decided for the foreach - update doc.
