+- Separate assignment and logical test statements.  In other words, you
+should write statements like the following:
+@code
+// separate statements should be preferred
+result = foo();
+if (ERROR_OK != result)
+	...
+@endcode
+More directly, do @b not combine these kinds of statements:
+@code
+// Combined statements should be avoided
+if (ERROR_OK != (result = foo()))
+	return result;
+@endcode
