  ##  either use keys or do NOT use keys; do NOT mix in a single fixture file

  ### support autogenerate key from first title value

  # if it looks like a key (only a-z lower case allowed); assume it's a key
  #   - also allow . in keys e.g. world.quali.america, at.cup, etc.
  #   - also allow 0-9 in keys e.g. at.2, at.3.1, etc.

  # fix/todo: add support for leading underscore _
  #   or allow keys starting w/ digits?
