Comment (by joedolson):

 Checking `! is_string()` has advantages in that it will also guard against
 other non-string types, should the value be passed as an array or object.
 That seems improbable, but it's hypothetically possible.

 The current case would cause problems in the relatively obscure case that
 the title of a page is 0. It's unlikely, but it is possible and I can
 think of legitimate use cases for it. I don't think it's urgent to make
 this decision for the next beta, but should be resolved before RC.
