+=======================
+
+Detects variable and function can be marked as static.
+
+Static functions and variables are scoped to a single file. Marking functions
+and variables as static helps to better remove dead code. In addition, it gives
+the compiler more information and can help compiler make more aggressive
+optimizations.

I'm not sure about automatic fixes for anonymous namespaces. For example, in my work project we keep single monolithic anonymous namespace, so function body move would be required.
