Prev: std::search versus strstr for std::vector<char>

According to the latest draft, there is no difference between direct-
list-initialization and copy-list-initialization in the process of
overload resolution. Besides, if there is an initializer-list-
constructor in the class, the braced-init-list is considered a single
argument and all constructors are candidates for overload resolution.
This enables the following example to be correct. Am I right?

#include <initializer_list>

struct Z {}; // dummy class

struct A
{
A (std::initializer_list<int>);
};

struct B
{
B (std::initializer_list<Z>); // adding such constr. to every
class
// it is never viable
B (A);
};

struct C
{
C (std::initializer_list<Z>);
C (B);
};

struct B
{
D (std::initializer_list<Z>);
D (C);
};

D d {1, 2, 3};
