Today we try a different format. Adam invites his neighbour, Don McKay, over to ask him questions. An interesting discussion on recursion, corecursion and the naming of the podcast unfolds.

"John was saying, we conclude that since modularity is the key to successful programming, dah, dah, dah, dah, dah. I think what he means by modularity is okay, we write our fold and it's like three lines long. Once that exists somewhere, we don't have to have that base case all over our code. We ended up programming a higher declarative level. The other reason is just I really like clean abstractions. There's more to learn but once you do, you're able to kind of have this language where you can talk about these things at a higher level"
