Yes absolutely - but very much pro-Lisp and the conclusions may not be
applicable for many purposes. The article is also referred on slashdot with
a very long discussion on Lisp pro/con.

I guess the power comes from seamlessly being able to write programs in
programs. You can do that in Ruby (which was also a wow factor), but I'm not
sure it can be done as elegant as in Lisp - but then I know very little
about this issue. Like you, I would like to learn more. My primary reason
for looking at Ruby is to gain programming power.

I recently looked at Erlang - the above article has left me wondering
whether you get the same mystical power in Erlang (which does have macros).
