AutoLISP is still my most fluent language, pleasantly surprised to see anything in it on HN. There's something fun about its idiosyncrasies, but I am genuinely so glad for modern IDEs, linters, tooling in just about every other environment. AutoCAD has severely neglected it, despite some large businesses built exclusively upon it.
Still your most fluent - that says something about how the language shaped thinking. The neglect is real; Autodesk clearly wants everyone on .NET, but there's a lot of institutional knowledge and working code out there that just... works. Part of why I built this: preservation. If AutoLISP fades from AutoCAD entirely, at least the workflow can live on in the browser.
