[commonlisper]

In case it is not apparent to others, Lisp-Stat (OP of this story) and singaporecode (parent commenter here) are different people.

The account singaporecode and a few other related accounts really look dubious. They are promoting a few websites created by the same author: https://hn.algolia.com/?query=ashok%20khanna&type=all

The comments by singaporecode where they say "I should sponsor the guide’s author" (when the author is himself/herself/themselves) and "I found online" (where they published it themselves) are clearly deceptive self-promotions of https://ashok-khanna.medium.com/ and https://github.com/ashok-khanna but do notice that they are unrelated to Lisp-Stat.
