Puh-lease. Patches are so Last Millenium.

We shall do this via the most obnoxious implementation technique yet
discovered: Pair Programming Via USENET.

Here:

  def test_list_of_lists
    tok = []
    @yaml.tokenize( "- [ foo ]" ) { |t| tok << t }
    assert_equal [ :punct, "-" ], [ tok.first.group, tok.shift ]
    assert_equal [ :normal, " " ], [ tok.first.group, tok.shift ]
    assert_equal [ :punct, "[" ], [ tok.first.group, tok.shift ]
    assert_equal [ :normal, " foo " ], [ tok.first.group, tok.shift ]
    assert_equal [ :punct, "]" ], [ tok.first.group, tok.shift ]
  end

I got each assertion working except the last, by adding this:

  class YAML < Tokenizer
....
          when scan(/:\w+/)
            start_group :symbol, matched

          when scan(/(\s*)\[/)
            start_group :normal, subgroup(1)
            start_group :punct, "["
....

However, now I can't find where to get the closing ] out of the :normal
string " foo ]".

After we do that, we need , working, and we need [ at BOL, without the -.
