You&#x27;ve done great work. But speaking as an old lisp programmer it doesn&#x27;t seem useful.<p>Code, for me, is a means of communication with both the machine and the human reader. The machine doesn&#x27;t care about lisp indentation but code format matters when trying to communicate with human readers. Communication with future readers, including yourself, is what makes programs maintainable.<p>Pretty-printing is fine since the code format follows a standard, which makes it easy to ignore and easy to read, generally a &quot;good thing&quot;. On the other hand, there is information in the choice of code format, similar to the information found in a poetry format.<p>Properly indented code is &quot;good code&quot; and, over time, is likely to be what flows from your fingers regardless of the editor. But excellent code is an art form that requires thought. Lisp is a language where indentation is meaningless but shape communicates. It is not something to delegate to an editor.
