Emacs is my favourite software, but elisp is one of my least favourite lisps. The other day I stumbled upon Shen language after some years and noticed it now has BSD license and an elisp implementation. I tried to add it to spacemacs and, to my surprise, it just worked. When I have some spare time the next thing I'll do will be to learn some Shen and see if for shell scripting it is an improvement over elisp.
