Another sign that the new Transient package by @magit_emacs has a good design: a thoughtful comparison with similar packages in the ecosystem! https://magit.vc/manual/transient/Comparison-With-Other-Packages.html#Comparison-With-Other-Packages

@krinkle A surprising number of PL design workarounds are "just add another equals sign" 🙃
One interesting design choice in Emacs that I haven't seen in other editors: reserved shortcuts.
An Emacs extension shouldn't use F5 through F12, or Ctrl-c LETTER. This lets users configure their own shortcuts. https://www.gnu.org/software/emacs/manual/html_node/emacs/Key-Bindings.html
Does it exist elsewhere? I miss it in VS Code, where e.g. all the Fn keys are already assigned.
Sometimes programming tools are so good that you miss them when using other languages. I see these mentioned the most frequently:
* IntelliJ (for Java)
* Slime+Emacs (for Common Lisp)
* Pharo (for Smalltalk)
I'm struck that they all have bespoke UIs.
