macrostep VS speed-of-thought-lisp

Yes. Most people seem to use use-package without really understanding what it's doing. I love use-package, but I never edit use-package declarations without macrostep (also (setq use-package-expand-minimally t)) to see what it expands to.

Macrostep made me 10-20x faster at diving into, profiling, and debugging emacs lisp codebases.

Try macrostep to interactively expand these nested macros.

Try speed of thought lisp and see if you like it, or yasnippet. I think it is great, I can just type acronym (actually could be any abbrev) and space and it completes, however I dislike the fact that it requires me to remember acronyms. But I do use it for some of the more usual stuff like with-current-buffer is wcb, require is r and so on.

Paredit, Speed-of-thought lisp, Helm, perhaps Lispy but I am not using it myself. I found expand-region to work really well when writing and modifying elisp. lisp-extra-font-lock if you want some more blink (and font-lock-studio). Helpful is very good to have instead of built-in help, it displays the source code by default as well as symbol properties. It is a very informative learning experience to see how built-in stuff is implemented. I am quite lazy to press extra in built-in help to see the source code, but with Helpful, you get it auto in the same window, whicih is great for learning. Seeing symbol properties is sometimes a time saver so you don't have to M-: and type an Elisp function to see the symbol properties when debugging. Learn Edebug, it is very useful built-in application for Emacs Lisp development.
