    # The symbol_views plugin allows match blocks to return
    # symbols, and consider those symbols as views to use for the
    # response body.  So you can take code like:
    #
    #   r.root do
    #     view :index
    #   end
    #   r.is "foo" do
    #     view :foo
    #   end
    #
    # and DRY it up:
    #
    #   r.root do
    #     :index
    #   end
    #   r.is "foo" do
    #     :foo
    #   end
