+misc-replace-memcpy
+===================
+
+Replaces ``memcpy`` with ``std::copy``. This allows the compiler to decide on
+the most performant implementationon. Parenthesis are added devensively to
+preclude the summation from taking precedence.
+
+Example:
+
+.. code:: c++
+
+    std::memcpy(dest, source, sizeof dest);
+
+    // transforms to:
+
+    std::copy(source, (source) + (sizeof dest), dest);
