  @kevincox Thanks for the reviews !

  That's an interesting idea. I expect it to solve my gripes with `ensure_undecided()` neatly. I'm not sure how it'd fare on the Python side, and probably wouldn't do it in the bindings to maintain compatibility, but I'll play with it a bit.
  Maybe this could be a good topic for a follow-up ?
  Note: I still have the various sampling methods to submit today or tomorrow, but I think they would play well with that idea.
