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.
