  • move is_Gδ_irrational etc to a new file topology.instances.irrational;
  • prove that a small ball around an irrational number is disjoint with the set of rational numbers with bounded denominators;
  • prove order_topology, no_top_order, no_bot_order, and densely_ordered instances for {x // irrational x}.
