Well, the other problem is that the stuff the article says about Lisp is incorrect and gravely misinformed.
For instance:
> This makes the left and right parenthesis unchangable from within the language
The parenthesis character in Common Lisp can be redefined, even just temporarily, to anything you want.
This is a misunderstanding and shouldn't be in your opening play.
It sounds like the author thought of something they felt was neat, but felt they had to justify its existence first by a quick pot-shot at another similar thing. It would be more effective if either it were correct, or they just described their own creation from the get-go.
