I've prepared a 30 min video presentation introducing D2288 C++ Designated Arguments and posted it here:
The design is mostly complete and the current plan is to:
(1) write the formal wording
(2) complete the implementation
(3) propose merging and shipping implementation as a non-standard extension under feature flag `-fdesignated-arguments` in clang
(4) propose standardization on the basis of existing practice from (3).
We welcome any questions, comments or other feedback.
Also, if anyone wants to volunteer helping out / supporting steps (1) or (2) that would be greatly appreciated.
Enjoy,
Andrew.
