Thanks!
I didn't do it like this out of fear it may be too slow. But it turns out to be
faster:

  overhead: 0.00
  plain_grouping: 0.27
  update_grouping: 0.43
  plain_adopt_grouping: 0.68
  autoinit_grouping: 1.15
  autoinit_setattr_grouping: 1.08 # yours
  autoattr_grouping: 1.06

I am amazed. Very good!

Cheers,
        Ralf
