    @h = Hash.new
  end

  def set(key, value = nil, &block)
    @h[key.to_s] = if block_given?
                     HashBuilder.build &block
                   else
                     value
                   end

  def self.build(&block)
    builder = HashBuilder.new
    if block_given?
      builder.instance_eval &block
    end
    @h
  end

  def method_missing(symbol, *args)
    set(symbol, *args)
  end
end

hb = HashBuilder.new

r = hb.build {
  wibble 42
  wobble 43

  wiggle {
      set "a", 1
      set "b", 2
  }

  banana 25

   set "big-thing", 42
}

puts r.inspect

think we can get to:

default "xmlapi" do
foo "bar"
end

shared_service "blah" do
baz "cow"
end
