2020-11-14 14:26:29 <Zetagon> kuribas: emacs-lisp is far from a bad language. it has the advantage of being a lisp so a lot of things can be improved with libraries. It has borrowed a lot of functionality from common lisp for example with cl-lib. But yeah it's not the best language either

2020-11-14 14:27:17 <kuribas> Zetagon: I find it aweful, because: no propper lexical scope, though that's fixed in later versions, no namespaces, one global interpreter thread, etc...
2020-11-14 14:27:25 miseenplace[m] joins (miseenplac@gateway/shell/matrix.org/x-ywbimksbsmmywabw)

2020-11-14 14:30:57 <Zetagon> wiktionary seems to agree with ski

2020-11-14 15:21:56 <fendor> cabal does not like literate haskell files
