I think that's because there are cases when Marshal won't work. Adding a
core feature that "sometimes works" is not something I'd do :)

Quoted from ri Marshal:

   Some objects cannot be dumped: if the objects to be dumped include
   bindings, procedure objects, instances of class IO, or singleton
   objects, a TypeError will be raised.
