// Nyash micro benchmarks using TimerBox (script-level)
// How to run:
//  - Interpreter:           ./target/release/nyash examples/ny_bench.hako
//  - VM:                    ./target/release/nyash --backend vm examples/ny_bench.hako
//  - VM+JIT (fast path!):   NYASH_JIT_EXEC=1 NYASH_JIT_THRESHOLD=1 ./target/release/nyash --backend vm examples/ny_bench.hako
