Here's @drak's Wisp: Lisp, minus the parentheses https://bitbucket.org/ArneBab/wisp
Arne gave a talk about it at this FOSDEM, highly recommended: https://video.fosdem.org/2019/K.4.201/experiencewithwisp.webm
I've written about it before: https://dustycloud.org/blog/wisp-lisp-alternative/
And, relevant to Golem, here's downloading chunked files over a p2p network in Wisp code: https://bitbucket.org/ArneBab/wisp/src/cca15c7abc86a500a313315344f9f46bc90e9ce8/examples/downloadmesh.w?fileviewer=file-view-default
