I wish someone would shed som light on this as inline namespaces 
is what libraries will use in the future in order to do 
versioning and  target different architectures, the one marked 
"inline" is made active and can be directly accessed through 
"X::decl" or "X::version1::decl" in c++:

namespace X {
      inline namespace version1 {
           decl....
      }
      namespace version2 {
           decl....
      }
}

Seems to me that D needs to embed clang and that the current 
bindings-only approach will not survive C++11 and later standards.
