Thanks for contributing from a Smalltalk perspective. Yes, you're right: as I've repeated several times, when I say "repl-driven programming", I am not talking about a repl window or a command-line shell. I'm talking about the actual read-eval-print loop, the runtime feature that reads input, evaluates it, and presents results. I'm talking about a language and runtime that is designed to be modified while it runs by evaluating incremental changes offered interactively by the user. It's not about a prompt in a terminal. It's about a software-construction system that is designed to be modified interactively as it runs. Smalltalk is quintessentially that. It seems like some folks have encountered a repl UI with a prompt in a terminal and jumped to the conclusion that this specific kind of UI is the repl. It isn't. It's one particular kind of UI for a repl. There are others, and there have been others since forever. For heaven's sake, Smalltalk 76 had other kinds of UI for its repl in, well, 1976.
