He said "I rewatched part of Stu's "Repl-Driven Development" talk, and it's terrific, but it's a bit more advanced than he's probably ready for." (but I agree it's a great talk that focuses on the benefits of RDD)

Off topic but I really liked the suggestion in this talk to just throw all random scratch repl code into a text file in the same directory and make a new one every month. I've been doing this since I watched this talk and i've felt it's been very beneficial having a place to just stash a bunch of useful code that doesn't belong anywhere else

@U0502D2GL thanks, though! @jjttjj I played with that a bit, and it didn't feel compelling enough (to me personally) that I stuck with it. On the other hand, I have cider save my repl-history every time the repl exists.
