# Development Roadmap

## Phase 0: Compiler Core ✅
- [x] Clojure Reader (EDN parser)
- [x] AST → Nim Emitter
- [x] CLI (`compile`, `run`, `read`)
- [x] Special forms: `def`, `defn`, `fn`, `let`, `if`, `do`, `quote`
- [x] Arithmetic operators
- [x] Human and JSON REPL

## Phase 1: AI-Native Tooling 🔄
- [x] JSON REPL mode
- [x] Batch evaluation
- [x] Structured errors
- [ ] File operations (`file/read`, `file/write`)
- [ ] Git operations (`git/commit`, `git/push`)
- [ ] nREPL protocol compatibility

## Phase 2: Persistent Data Structures
- [ ] Persistent Vector (HAMT)
- [ ] Persistent Map (HAMT)
- [ ] Persistent Set
- [ ] `conj`, `assoc`, `dissoc`, `get`, `get-in`
- [ ] `nth`, `first`, `rest`, `last`, `count`

## Phase 3: Clojure Core Library
- [ ] Seq functions: `map`, `filter`, `reduce`, `range`
- [ ] String functions: `str`, `pr-str`, `slurp`, `spit`
- [ ] Meta: `meta`, `with-meta`, `type`

## Phase 4: Macro System
- [ ] `defmacro`
- [ ] `syntax-quote`, `unquote`, `unquote-splicing`
- [ ] `gensym`
- [ ] Core macros: `->`, `->>`, `and`, `or`, `when`, `cond`

## Phase 5: Nim Interop
- [ ] `nim/import` — Import Nim modules
- [ ] `nim/call` — Call Nim functions
- [ ] C FFI declarations

## Phase 6: Optimization
- [ ] AOT project compilation
- [ ] Module caching
- [ ] Self-hosted REPL (compile in memory)

## Phase 7: Concurrency
- [ ] Atoms (CAS)
- [ ] Agents
- [ ] core.async channels (simplified)
