In C++ it is possible to use the
Annex D.2 [depr.static]
The use of the static keyword is deprecated when declaring objects in namespace scope (see 3.3.6).
In C++ Standard Core Language Defect Reports and Accepted Issues, Revision 94 under 1012. Undeprecating static` they note:
Although 18.104.22.168 [namespace.unnamed] states that the use of the static keyword for declaring variables in namespace scope is deprecated because the unnamed namespace provides a superior alternative, it is unlikely that the feature will be removed at any point in the foreseeable future.
Basically saying that the deprecation of
static doesn't really make sense. It won't ever be removed from C++, and it's still useful because you don't need the boilerplate code you need with unnamed namespaces, if you just want to declare a function or object with internal linkage.
