Should mark this explicit.

I think the private has to go inside the #if or we won’t compile with it off.
Maybe that’s one reason for the red I see below in EWS.

Can delegate be a reference instead of a pointer? I think that would be much

Also, I think this constructor should be marked explicit.

I don’t think we have working constexpr on the Windows compiler. We maybe were
working around it with a macro? I’d ask Anders about this.
