docs: Temporarily ignore any callbacks from one or more callback properties
  
      This is a context manager. Within the context block, no callbacks will be
      issued. In contrast with :func:`~echo.delay_callback`, no callbakcs will be
      called on exiting the context manager
  
      Parameters
      ----------
      instance
          An instance object with callback properties
      *props : str
          One or more properties within instance to ignore
  
      Examples
      --------
  
      ::
  
          with ignore_callback(foo, 'bar', 'baz'):
                  f.bar = 20
                  f.baz = 30
                  f.bar = 10
          print('done')  # no callbacks called
