There was a thread about Franz Lisp founder where he explains that DARPA D.A.R.T project was done in C, about 30M LoC, and failed hard, while the Lisp implementation was running nicely, easy to fix in hours not days.
I'm not an experienced lisper, but it's not the first time I read this kind of report.
- rwallace 5y agoThat sounds interesting! Google doesn't find any mention of that, only https://en.wikipedia.org/wiki/Dynamic_Analysis_and_Replanning_Tool https://en.wikipedia.org/wiki/Dynamic_Analysis_and_Replannin... that says DART, far from failing hard, was a huge success. Do you have a link to the thread?

- rwallace 5y agoThanks! Right, so the successful version was the one written in Lisp. Okay, that's actually understandable. At that time, managed languages were not widely used, and C is really not a good choice for that kind of project. If those are the two options, I can certainly see how Lisp would do better.
