      """ Extract an iterable from the current line of a file-like object.
  
      Args:
          f (file): the file-like object to read from
          container_type (type): type of the iterable that will be returned
          item_type (type): type of the values that will be elements of the returned iterable
          separator (str): the separator between two consecutive items
  
      Returns:
          The extracted iterable
  
      Example:
          The file "a.input" contains three lines and three comma-separated digits on each::
  
              >>> with open("a.input") as f:
              ...     print(utools.files.read_multiple_items(f, list, int, separator=","))

              ...     print(utools.files.read_multiple_items(f, tuple, float, separator=","))
              ...
              [1, 2, 3]
