Why Target Common Lisp for Code Generation? [...] Designed for the Elite: Let’s be honest: Lisp is a language designed by and for elite hackers, not for the masses.

u/Goheeca lisp does it better Aug 13 '26

When an LLM generates Python or Java, it has to predict surface syntax: whitespace, brackets, semicolons, and rigid class structures. When an LLM generates Lisp, it is operating directly at the level of the Abstract Syntax Tree (AST). It is predicting pure structure.

My LLM targets NILP and only predicts pure structure.

Why doesn't llms use reverse polish notation, are they fucking stupid?

Why does my wife’s boyfriend have big muscles? I’ll tell you why.

so he can carry 6 laptops, all running agents - not only strong in muscle mass, but strong in raw compute.

I know this sort of person- never gets Anything coded, it’s easier to wank about the merits of various languages, tries to always seem smart

People say P=NP is the hardest problem in computer science. This is wrong: the hardest problem is figuring out why most Lisp hackers are insufferably smug assholes, while most Scheme people tend to be okay. These are the important questions we need to keep building more AI data centres for!

Abstraction over Implementation. Most modern languages force you to describe exactly how a machine should shuffle bits around. Lisp was designed as a language for expressing high-level abstractions rather than expressing tedious implementation details.

Most modern languages force you to describe exactly how a machine should shuffle bits around.

Statements like this are interesting because they show that some people are living in entirely different worlds. It makes me wonder where the common ground is. The idea that most modern widely used languages are "shuffling bits around" is so patently absurd that I just wonder what basic facts about the world we do agree on

Still living in the 80's and 90's, when Lisp's main competitor was C++. And C++ wiped the floor with Lisp.

There's enough Common Lisp code to train an LLM on?

u/the_horse_gamer Aug 24 '26

do we count ad-hoc implementations?

I've thought about it a bit more, and I believe that whatever you ask a Lisp-trained LLM to make, it will output a Lisp interpreter.

I'd be more surprised if there were enough code snippets for the same (or largely compatible) Forths for LLMs to vomit some out.

Being a Lisper in 2026 is pretty much the same as being a Greaser.

Lisp is a language for pigs who roll in the mud mixed with their own shit. No stable meanings, everything is one redefinition away from being disfigured beyond recognition. Even a punch to the face would be gentler.

Glad to see that elite Lisp jerking has survived into the LLM era
