There was a problem hiding this comment.
The phrasing here is a bit weird, this parses as "shall be (friend), (inline), or (constexpr or an explicit-specifier)". How about:
shall be
friend,inline,constexpr, or an explicit-specifier.

Change to [dcl.init.aggr] ignored, as the relevant wording was deleted by P1008R1 (applied by 2018-06 CWG Motion 12).
Parenthesized names for explicit constructors and conversion functions are still valid if the name doesn't immediately follow the explicit keyword. Add an example using explicit(true) as a hint indicating how to get the same effect. Change affected subclauses from [dcl.fct] to the somewhat-more-precise [class.ctor] and [class.conv.fct].
