Crate oxur_repl 

Oxur REPL

Provides a Read-Eval-Print-Loop with three-tier execution:

• Tier 1: Calculator mode (interpret simple arithmetic only) - <1ms
• Tier 2: Cached & loaded (execute from already-loaded library) - ~1-5ms
• Tier 3: Just-in-time (compile, cache, and load) - ~50-300ms

Based on ODD-0018: Oxur Remote REPL Protocol Design and ODD-0026 v2.0: Oxur REPL Evaluation Strategy
