`span::operator[]` returns `atomic_ref` That is all that is required. The intent is that construction / setup of the span more efficient than construction of each individual atomic_ref.

From abstraction perspective, `a[i][j][k]` is syntax for _array of array of array_ vs. multidimensional array. From implementation perspective, reasonable performance with layout extensibility requires incredibly delicate template meta-programming and aggressive...

P0009 has passed through LEWG for the next library TS without the _array of array of array_ dereference. Introduce a new paper to add the interface once it in the...

The accessor policy changes introduced from R5 to R6 were never reviewed with LEWG and thus already necessitate revisit with LEWG, unless stripped out entirely and submitted as a follow...

1. The straw polls were for variadic or not properties, with accessor policy as a single template parameter. 1. D0454r1 was a draft version that did not appear in the...

From LEWG notes (included in #46): Poll to remove nullptr_t constructor: 4-5-3-0-0

@tkoeppe : We are systematically identifying the issues that must be addressed. At this point the complexity appears to be a breadth issue, not a depth issue. Primarily identifying those...

We need a taxonomy of incomplete types. The standard talks about incomplete types in many ways: _cv_ `void`, _incomplete class_, _array of unknown bound_, _incomplete type that cannot be completed_,...
