>Why is lisp and related languages so popular on this chan?
An active Lisp group was migrated here. You can find it here: >>18486>I am currently learning C++ and wonder why I barely see any languages such as that on here.
There is a C++ thread here: >>11025>Is there something that is missing out in modern languages that lisp has?
Lisp has homoiconicity, one representation for a program and data, which easily allows for programs that modify programs. This enables powerful metaprogramming.>Is Lisp a must know language?
No language qualifies as that. I doubt it will hurt you, however.
Now, this question isn't appropriate for its own thread, considering that there already exists Lisp threads and whatnot, so this is being locked now.
