// PR c++/91364 - Implement P0388R4: Permit conversions to arrays of unknown bound.
// { dg-do compile { target c++2a } }
struct A {
A();
A(const A(&)[2]);
};
using T = A[];
using U = A[2];
// t binds directly to U{} now. Before it bound indirectly to a temporary
// A{U{}}. ??? But we don't do it now; see reference_binding and the
// BRACE_ENCLOSED_INITIALIZER_P block.
A (&&t)[] = {U{}};
U u{};
T &
foo ()
{
// This didn't compile before P0388R4: invalid initialization of non-const
// reference of type 'A (&)[]' from an rvalue of type
// '<brace-enclosed initializer list>'.
return {u};
