A closing parenthesis was missing in its Lisp source code. Took 3 hours and 9 engineers to find where
I don't remember now, but it wasn't AT ALL the big issue that I initially anticipated. I just mention it, because your comment made me realize that I also don't understand WHY it wasn't an issue!
An editor that cannot match parentheses, brackets and braces, or auto-indent in at least a rudimentary way is not very usable for working in anything.
LMK if you figure out why! Because whenever I'm refactoring in a bracket-heavy language, it's almost guaranteed that, every so often, the parser starts throwing syntax errors, and I need to stare at something like `)]})})` for a while.
What tooling am I missing that can prevent this from happening? I use auto-formatters and rainbow bracket colorizers whenever possible, and they're great! But in no way prevent this from happening.
Every parenthesis in Lisp world is unique like a snowflake, and they come in pairs.
I think you just discovered parenthesis entanglement theory :)
Unless their foundation air-dropped them a couple of Starlink units alongside their seasonal food and goods supply run.
