There are many impressive Lisp dialects which aren't mentioned here like Mark Tarver's Shen programming language and John Stutts Kernel programming language, so I am just going to vote for Lisp which hopefully covers most of these dialects. I have been a Lisper for over a year. I am not particularly impressed with most things which aren't Lisp based or which aren't at least functional. In particular, I am not impressed by Python. Admittedly, I am biased towards functional languages like Lisp because I am a mathematician.
