class_docstr: Make blob objects behave like Python strings.
  
  Expects that classes that use this mixin to have a _strkey() method that
  returns the string to apply string methods to. Using _strkey() instead
  of __str__ ensures consistent behavior between Python 2 and 3.
docstr: Returns the length of the raw text.
docstr_tok: ["Returns","the","length","of","the","raw","text","."]
code: def __len__(self):
      """Returns the length of the raw text."""
      return len(self._strkey())
