Subject: to_yaml and options hash


iccording to the docs, this should emit the version:

  ~/eg/ruby > ruby -r yaml -e 'print([0,1,2].to_yaml(:UseVersion => true))'

but it simply outputs

  ---
  - 0
  - 1
  - 2

other options seem to be ignored too (:Separator, etc).  my questions are

  a) what's up with the options hash?  it does not seem to work the way the
  docs imply:

  ...     
    puts [[ 'Crispin', 'Glover' ]].to_yaml( :Indent => 4, :UseHeader => true, :UseVersion => true )
    # prints:
    #   --- %YAML:1.0
    #   -
    #       - Crispin
    #       - Glover
  ...     

  ~/eg/ruby > ruby -r yaml -e "puts [['Crispin','Glover']].to_yaml(:Indent=>4,:UseHeader=>true,:UseVersion=>true)"
  --- 
  - 
      - Crispin
      - Glover



  b) is there an option that will cause

      [ 0, 1, 2 ].to_yaml

      to be emitted as

        [ 0, 1, 2 ]

      rather than

        ---
        - 0
        - 1
        - 2


thanks for any assistance.
