Fun project, but I wonder how difficult it would have been to get Fennel to run in Guile-Lua? The article did not get into any details or even mention if it was seriously attempted. Fennel supposedly supports "Lua 5.1, 5.2, 5.3, 5.4, or LuaJIT" so a Lua implementation that is "in the realm somewhere between Lua 5.1 and 5.2" is not obviously not supported? https://fennel-lang.org/setup https://fennel-lang.org/setup
