  1. i like the structure of Hutton's explanation. especially how he first introduces general recursion with rec f. but, he could have brought some extra attention to the fact that the result of rec f is a function. i think that this makes it extra difficult for people to understand (lot's of people confused in the comment section). working out the examples would have helped. on the other hand people might not really understand unless they come to the solution themselves. difficult dilema

  2. i think the arguments he chose as the result for TRUE and FALSE are intuitive. it's similar to the if statement in imperative languages in an imperative language you could write: if(1=1) {return 2;} else{return 4;}... in his examples you could use TRUE and FALSE as an if statement: (1=1) 2 4 the order of the possible results is the same it's easy to remember
