alt Hacker NewsI think half the article talks about why CL is good because it can resume from an exception, and half the article talks about why DSLs are good.
I think others have pointed out that most modern scripting languages can halt at exceptions without unwinding the stack. Python & Node both support this with core tooling.
As for DSLs, they constrain the LLM which generally helps with code quality. However why implement your DSL in the unconstrained chaos of CL? You can write DSLs in Rust which gives you static typing, a borrow checker, and clippy.

Common Lisp has these capabilities _without_ dev tooling, via its:
- Conditions[0]
- Evaluation and Compilation[1]
I use both extensively while developing, debugging and analysing. With SLIME (this is a standard and very very slimmed out development aid) you add a debugger hook that allows restart, return from, move down, move up and etc into your available RESTARTs.

What’s missing in most languages is truly native hot reload. Python, for all its dynamicism and being lisp for dictionaries, surprisingly can’t really do it. Maybe node can, but as far as I can tell typescript can’t and I’m not letting the shoggoths touch plain js.
