Tested with dmd 2.63.2. Trying to return a ref int to a local int errors correctly as does a `scope A a = new A()`.

---

import std.typecons, std.stdio;

class A { }

// Using auto ref because I don't know how to get the type of scoped
// (I guess I should file this behavior as a bug too)
auto ref fun()
{
	auto a = scoped!A();
	writefln("%x", &a);
	return a; // Compiler should output:
	          // Error: escaping reference to scope local a
}

void main()
{
	auto a = fun();
	writefln("%x", &a);
}
