Sorry. I didn't intend to argue against either, just to point out that loading compiled files was sometimes a reasonable alternative. Then, because Poplog can't compile files, it's more important that it provide incremental worlds. I would not consider saved worlds of any sort a point against any Lisp that provided them. >I don't know of any professional-quality Lisps that don't provide >saved worlds. Neither do I. Moreover, I wish more of them provided incremental worlds so that the resulting files would be smaller.
