+  * if (debug_level (SomeDebugLevel) && other_optional_conditionals) {
+  * 	debug_stream() << "Debug output" << std::endl;
+  * }
+  * \endcode
+  *
+  * The order of the conditionals in the if-clause is important.
+  * The checks specified in \a other_optional_conditionals are only
+  * optimized out if \a debug_level() is placed before it with a
+  * logical and (short-circuiting).
