Because it uses the C++ type system to restrict the number of possible
interpretations about the valid operations on the returned value, thus
communicating information that would otherwise go unspecified.
Sometimes this lets the compiler help spot problems with the program's
correctness. Even if not now, it can once in a while save your ass as
the program evolves over time.
