Excellent discussion of how REPL programming enables you to write code incrementally, going beyond what you can do with e.g. ipython or ghci.

I frequently find myself running: $ slowish $ slowish | jq $ slowish | jq | grep I feel there must be a better way to build up pipelines incrementally without re-running. I could save each output to a file, but it's more verbose, and most of these tools have nicer output when stdout is a TTY.

The Zen of Emacs, and the ability to extend *anything* incrementally, contrasted with VS Code design principles:
A spiritual successor to Emacs
I’ve been writing Python since version 1.5.2, and I think Guido von Rossum is one of the best language designers of our time, but I was a bit taken aback when on a recent Lex Fridman podcast he said, “To me, VS Code, in a sense, is a spiritual successor to Emacs.” His rationale for that claim: The key part of Emacs is that it’s mostly written in Lisp … There’s a core implementation that can read the file, put bits on the screen, and manage memory and buffers. Then, what makes it an editor full of features is all the lisp packages and, of course, the design of how the lisp packages interact with each other and with that base layer of the core immutable engine.
