Would love to see a video of what this actually means. I'm not sure I've ever written code for which I can use a REPL in any meaningful way so I must be doing it wrong. Videos of actual real world coding/debugging (not examples that are too simple and therefore not real world) would probably be very enlightening. I mostly do graphics stuff and there are 70 lines of setup until I get to the 1 line that executes something based on the 70 lines of setup. But even in non graphs code my program 1000s of lines, all of which have to execute where as a REPL is one line at a time so yea, a video would really help see how to apply this.

It's easier in some languages than others, but I would say the most common case is in Python (partially due to ease of dropping a REPL, partially due to lack of compile-time checks). The one line of code you always should have at your disposal is: from IPython import embed; embed() Basically, if you have an error and can't figure out what's happening within a few seconds, stick that line in before the error and Python will give you a REPL to play around with. It's like GDB but way better.
