Lispers were having fun badmouthing other languages for no good
reason:

"""
Don't you realize how ugly Ruby syntax is?

Here is in 150 lines of lisp, a simplified lisp reader that is able to
read all the lisp syntax needed to write it.

Try to parse Ruby syntax in Ruby and see how useless a language it
is.

Of course you don't like it when I point out just how wrong you are.
