-Unlike every other Clojure dialect, this project has **zero dependency on the Java ecosystem**:
-
-| Dialect | JVM? | Java Ecosystem Dependency |
-|---------|------|---------------------------|
-| Clojure (JVM) | ✅ Required | Full — runs on JVM, uses Java stdlib |
-| ClojureScript | ❌ | Heavy — Google Closure Compiler, JS ecosystem |
-| Babashka | ❌ | Medium — GraalVM native-image, still JVM-based |
-| **Bara Lang** | ❌ | **None — completely standalone** |
-
-### Why?
-
-- **Native Performance** — No JVM warmup, no GC pauses, C-speed execution
-- **Tiny Binaries** — Single-file executables, often under 1MB
-- **Nim Ecosystem** — Direct access to Nim and C libraries via FFI
-- **AI-Native** — JSON REPL, batch evaluation, AI-assisted error messages and code generation
-- **True Independence** — No JVM, no GraalVM, no Java stdlib, no Google Closure

 ### 1. Completely Independent from Java
-This is the **only** Clojure dialect that does not depend on any part of the Java ecosystem — not the JVM, not GraalVM, not the Java standard library, and not Google Closure Compiler. The entire toolchain is self-contained: Clojure source → Nim source → C source → native binary.

 The same Clojure code compiles to:
 
 | Target | Status | Use Case |
 |--------|--------|----------|
 | **Native binary** | ✅ Ready | CLI tools, system programming, servers |

 | **WASM** | ✅ Ready | Browser, serverless, edge computing |
 | **JavaScript** | ✅ Ready | Frontend, Node.js without 50MB JVM |
 
 ### 4. AOT Compiler — Not an Interpreter
-Full ahead-of-time compilation like ClojureScript, but without the JavaScript/Google Closure dependency:
-- Fast runtime execution at C speed
-- Small binary sizes with no interpreter overhead
-- REPL uses a hybrid model: tree-walking interpreter for fast feedback (<1ms eval), AOT compilation for production builds
+Full ahead-of-time compilation with C-speed execution and binary sizes under 1MB. The REPL uses a hybrid model: tree-walking interpreter for fast feedback (<1ms eval), AOT compilation for production builds.
 
 ### 5. Nim/C Interop Instead of Java Interop
 Direct FFI to the Nim and C ecosystem:
 ```clojure
 (nim/math/sin x)
 (nim/strutils/toUpper s)
+(nim/json/write-value-as-string data)
 ```
-Nim modules are auto-imported. No JNI, no JVM bridging, no Java interop overhead.

 - **AI code generation** — `(ai/generate "quicksort")` in REPL
-- **AI optimization hints** — `(ai/optimize code)` suggests algorithm improvements

 ### 7. Concurrency Without the JVM
 - **Atoms** — Compare-and-swap semantics
 - **Agents** — Async state updates with `send`/`await`
 - **core.async channels** — `chan`, `>!`, `<!`, `go` macros — CSP-style concurrency without JVM threads
