By Lisp, I mean all the Lisp programming languages in a whole.
I've been told how amazing Lisp is and know that many languages have been inspired by Lisp. But, I wonder if Lisp still has any exclusive design feature that just cannot be done in any other language.
Update my question (thanks to @gnat's advice)
The reason I asked the question is that recently, being an amateur programmer myself, I begin to learn Clojure just for fun, and the result is that I found lots of Lisp-related posts and comments, saying but one thing: "Lisp is unique", but other modern PLs have already adopted, stole lots of ideas from Lisp, like, Conditionals, Recursion, Function as 1st class citizen. And even meta-programming can be done by many language.
So, I want to find out is it that I missed out something and "Lisp still is different"? If it is this case, I'd like to know what I've missed.
Or that I'm lucky because other modern languages have stole all the good parts from Lisp so that it's not necessary to dig into the parentheses Lisp world, and "Lisp was different".
