--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Not quite sure if this is valid: clang++ (trunk) accepts (with -std=c++2a)

void cat(const auto(&...s)[6]) { }
using punk = char(*)[];

int
main ()
{
  cat("Hello","world");
}

but not

void cat(const auto(&...s)[]) { }
using punk = char(*)[];

int
main ()
{
  cat("Hello","world");
}
