These @goto shenanigans are probably not worth it. :)

I'm fine with it. This sort of interactive input use case is actually one of the places where goto seems to actually be clearer and easier than anything else.

Added some news. Note that it is currently possible to jump to REPL frames. This could be done by saving all the inputs in the REPL and than possibly creating a temp file that gets opened in the editor. |

This PR allows you to jump to a stackframe by entering its number (showed in the stacktrace from pr #19569) in the REPL and then pressing CTRL+Q. The keybinding is just something I took, it can be discussed.
I did a small recording of how it plays out: https://asciinema.org/a/17k6tfwec6hm6q57nzlbns61g
