It doesn&amp;#x27;t define what the different cases of the mal Lisp value type should be, for example, or when to implement pretty much all of the &amp;quot;optional&amp;quot; extensions it mentions in the first or second chapter. Most of the forms in each chapter get a sentence explanation of what they do, at most, and I hit several snags where I read an explanation and thought I implemented it correctly, only to find out there was something subtly wrong with the obvious implementation.&lt;p&gt;Also, writing a Lisp in a purely functional language isn&amp;#x27;t the best :X Things like by-reference function environments and atoms are hard to implement if you&amp;#x27;re not Haskell, at least if you try in the method that the guide outlines...</text><parent_chain></parent_chain></comment><story><title>Mal – Make a Lisp, in 68 languages</title><url>https://github.com/kanaka/mal#mal---make-a-lisp</url></story>
