it's a serialization format, not a metalanguage.  the thing is it's a
__readable__ one:

     harp:~ > cat a.rb
     require 'yaml'

     hash = {
       "a" => 0,
       "b" => 1,
       "c" => 2,
     }

     open('hash','w'){|f| f.write hash.to_yaml}
     open('hash'){|f| print f.read}
     hash = open('hash'){|f| YAML::load f}
     p hash


     harp:~ > ruby a.rb
     ---
     a: 0
     b: 1
     c: 2
     {"a"=>0, "b"=>1, "c"=>2}
