Ruby is a denser functional language than LISP.
This is just not true! Sure sometimes you have syntax suger in Ruby that makes something smaller but othertimes you don't in lisp I can always make everything smaller with macros. I would bet that Ruby is not shorter for most programmes.
His hole argument is based around that in lisp you have wo write (lambda ....) and in Ruby you don't.
Ruby gives you about 80% of what you want from macros
Ruby may give you some of the power but there is a lot you cant do in ruby and its much, much harder to do those things.
Ruby’s libraries, community, and momentum are good
Thats nice but has nothing to do with being lisp.
Not saying anthing against ruby but this article is just very strange.
