#### Dependent namespaces <a id="temp.dep.namespace">[[temp.dep.namespace]]</a>
|

+
A namespace alias is dependent if it is introduced by a
|
| 4 |
+
*namespace-alias-definition* whose *qualified-namespace-specifier* (if
|
| 5 |
+
any) is a dependent qualified name or whose *splice-specifier* (if any)
|
| 6 |
+
is dependent. A *namespace-name* is dependent if it names a dependent
|
| 7 |
+
namespace alias.

[*Example 1*:
|

+
|
| 11 |
+
``` cpp
|
| 12 |
+
template<std::meta::info R>
|
| 13 |
+
int fn() {
|
| 14 |
+
namespace Alias = [:R:]; // [:R:] is dependent
|
| 15 |
+
return typename Alias::T{}; // Alias is dependent
|
| 16 |
+
}
|
| 17 |
+
|
| 18 |
+
namespace NS {
|
| 19 |
+
using T = int;
|
| 20 |
+
}
|
| 21 |
+
|
| 22 |
+
int a = fn<^^NS>();
