Lisp Languages

Lisp experts have showed various views about what Lisp languages are. I will quote what have affected my choice. Please note that the following excerpts are just quoted from the internet. Their views and ideas should be much deeper and they should have more meanings than I can imagine.

"Why Ruby is an acceptable LISP (2005)" randomhacks

"Functional programming is a good thing" Rationale

"Clojure." X/Twitter

"While I love the power of Lisp, I am not a devotee of functional programming. I see nothing bad about side effects and I do not make efforts to avoid them unless there is a practical reason. There is code that is natural to write in a functional way, and code that is more natural with side effects, and I am not a partisan of either way. I limit my campaigning to issues of freedom and justice, such as the injustice of nonfree software." How I do my computing

"Having expressions represented as lists, so that programs can easily operate on them, is the heart of Lisp." Emacs Mailing List
