Actually, that's pretty much the definition from yaml.rb:

module Kernel
     def y( x )
         puts x.to_yaml
     end
end

Kernel#y and Object#to_yaml are analogous to Kernel#p and 
Object#inspect. Both #y and #p are convenient for debugging and irb. And 
there's also #pp, which is nice to have, too.
