+fuchsia-default-arguments
+=========================
+
+Warns if a function or method is declared or called with default arguments.
+
+For example, the declaration:
+
+.. code-block:: c++
+
+  int foo(int value = 5) { return value; }
+
+will cause a warning.
+
+A function call expression that uses a default argument will be diagnosed.
+Calling it without defaults will not cause a warning:
+
+.. code-block:: c++
+
+  foo();  // warning
+  foo(0); // no warning
+
