class_docstr: Represents a variable-length list of child spaces.
  
  Example:
      self.observation_space = spaces.Repeated(spaces.Box(4,), max_len=10)
          --> from 0 to 10 boxes of shape (4,)
  
  See also: documentation for rllib.models.RepeatedValues, which shows how
      the lists are represented as batched input for ModelV2 classes.
code: def __repr__(self):
      return "Repeated({}, {})".format(self.child_space, self.max_len)
