Finished the Build Your Own Lisp book and already added some extra features. There are still lots of extra’s I want to add to the langue. I also really need to add some docs and examples, and maybe even tests.

The language is quite capable especially with the prelude that is embedded into to it. It even has things like switch statements, completely implemented in lzp. Lisps are really programmable programming languages.

(fun {day-name x} {
  case x
    {0 "Monday"}
    {1 "Tuesday"}
    {2 "Wednesday"}
    {3 "Thursday"}
    {4 "Friday"}
    {5 "Saturday"}
    {6 "Sunday"}
})
(print (day-name 4))

> "Friday"
