<pre>When there's no return outside of conditional/loop/switch statement, but a
function expects a return type, clang will generate a warning, as expected.
There is one special case, and that's a switch statement where one statement
will always be true because every possible input value has been covered. In
such case, clang shouldn't return a warning, much like gcc does at the moment.
An example for such code can be found at [1]. See also [2].
