There's also MoonLisp compiling to Lua, written in... MoonScript [0]. The output isn't pretty, but I'm looking for a lisp for NodeMCU, so I might give it a shot :), maybe combined with [1] due to way NodeMCU seems to work (interpreting / locally compiling files + little memory = you want to save on source length, including comments).
