@jackdaniel@functional.cafe Yes, this is fast. But most people won't see it, because they are in the grip of the myth that "Lisp is slow". You get the most mileage by comparing against things people think are fast, at least for certain tasks, like C or Fortran. For a venerable example of the art of making that comparison, Steele had a number of biting comparisons between MacLISP and Fortran back in the day. Here are a couple that had quite an impact on changing my views, back in ancient times: GL Steele, "Fast Arithmetic in MacLISP", MIT AI Memo 421, Sept 1977. https://dspace.mit.edu/entities/publication/81ec8fec-0598-49e9-9973-0abaf85fa6d7 GL Steele, "Debunking the expensive procedure call myth", MIT AI Memo 443, Oct 1977. https://dspace.mit.edu/entities/publication/77b3eea1-50be-4e3f-b578-264484ee0f1a
