     The repeat that we use here is called a tactical, or tactic combinator. The behavior of repeat t is to loop through running t, running t on all generated subgoals, running t on their generated subgoals, and so on. When t fails at any point in this search tree, that particular subgoal is left to be handled by later tactics.
