As it stands right now, though, yaml can't read it's own output, which 
strikes me as a fairly major issue;

   require 'yaml'
   fred = "Call the method #dave"
   str = YAML.dump(fred)
   fred1 = YAML.load(str)
   puts fred1     # => 'Call the method '

For me, this, combined with the stuct bug I mentioned over on -core, 
makes YAML unusable for my RI work. At the very least, shouldn't ::dump 
escape the output?
