Mikel Evins on REPL-driven programming:

Interactive development with a proper repl-driven environment is the exception. Most programming is done in other ways.

As a consequence, there are a lot of programmers out there who’ve never even heard of it, who have no idea that it exists. My intuition is that some fraction of those programmers would prefer well-supported interactive programming, and would benefit from it, if they just knew what it was.

Maybe if enough programmers are exposed to that style of programming then we’ll begin to see new tools that embrace it.
