When class is a reserved word, it's common to see klass as a var name. Amusingly, rustc has krate variables too!

rustc: support dumping the AST as JSON · rust-lang/rust@34ffe3c
This is mostly useful for working on rustc, when one is unfamiliar with the AST a particular construct will produce. It's a -Z flag as it's very much for debugging. Closes #10485

Playing with Claude and my new programming language has made me add features that it wants. I think they're reasonable. `for method in methods` -- custom syntax error explaining that `method` is a reserved word `echo 'println("hello world")' | garden` -- eval snippets from stdin

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.
