Why We Built ll-lang, a Statically Typed Functional Language for LLMs

Why We Built a Statically Typed Functional Language for LLMs to Write ll-lang is a language for one narrow, practical job: helping LLMs generate correct code faster by spending fewer tokens on syntax and getting compile-time feedback instead of runtime surprises. The problem with "AI coding" is not that models cannot produce code. They clearly can. The problem is that most mainstream languages give them the wrong feedback loop. When an LLM writes Python, TypeScript, or Java, two things usually happen at the same time.
