Mark NAD as suggested.

[ Post Summit, Alisdair adds: ]

Paper N2843 proposes an extension to the [[align]] attribute that further diminishes the need for this template. Recommend NAD.

Agree. The need for aligned_union is compelling enough to reinstate.

It is not possible to create a variant union based on a parameter pack expansion, e.g. to implement a classic discriminated union template.

Original proposed resolutuion:

Restore aligned_union template that was removed by LWG issue 856.
