So I certainly have no problem applying this.  But it occurs to me that
this file hasn't been touched since it was added in 2015, and nobody has
complained that it doesn't work with modern Python.  That leads me to
wonder if it's being used at all.

Assuming that there is value in keeping it, I wonder if a move to
samples/ might make sense?

Thanks,
