That’s not the preferred style. The preferred style (not counting indenting, which was only recently standardized) can be seen in functions like Node::isContainer. To take advantage of the warning GCC provides to help you make sure you cover all values of an enum, we leave out the default whenever possible.

Could you give a specific example in today’s WebKit code where a particular compiler is emitting a “not reached” warning?
