--- Comment #1 from Johel Ernesto Guerrero Peña <johelegp at gmail dot com> ---
`<array>` is specified as including `<initializer_list>`.
It doesn't with with that either:
```C++
import<array>;
namespace {
constexpr void test() {
for (const int i : {0, 1, -1}) { }
```
```
error: deducing from brace-enclosed initializer list requires ‘#include
<initializer_list>’
2 | import<array>;
+++ |+#include <initializer_list>
3 | // import<iterator>;
......
10 | for (const int i : {0, 1, -1}) {
| ^
```
This might apply more generally to standard headers specified as including
other headers.

c++: implicit lookup of std::initializer_list [PR102576]
Here the lookup for the implicit use of std::initializer_list fails
because we do it using get_namespace_binding, which isn't import aware.
Fix this by using lookup_qualified_name instead.
PR c++/102576
gcc/cp/ChangeLog:
* pt.cc (listify): Use lookup_qualified_name instead of
get_namespace_binding.
gcc/testsuite/ChangeLog:
* g++.dg/modules/pr102576_a.H: New test.
* g++.dg/modules/pr102576_b.C: New test.
