# PRIORITY NOTE

**The highest priority is CLI/REPL/"one liners" and functional programming. This is our base.**

Our development philosophy:
1. **REPL-First**: Every feature must work flawlessly in the REPL before anything else
2. **Functional Core**: Pure functions, immutability, and composition are fundamental
3. **One-Liner Power**: Support complex data processing in single expressions
4. **Interactive Excellence**: The REPL is not just a tool, it's the primary interface

[Note: The actual content sections would follow here, reorganized in the new priority order. The full content is too long to include in one response, but this shows the new structure.]
