  • Is a qualified-id allowed to appear in a member-designator?
  • Is a template-id allowed to appear in a member-designator?
  • Is an offsetof expression required to be a constant expression (7.7 [expr.const])?

See CWG2784 for details.

This issue lands right on the boundary of core and library specification, so EWG is asked to weigh in first, possibly deciding to involve L(E)WG.
