![]() This materially improves performance for programs that are recursion-heavy (as most Roc programs will likely be). ``` $ hyperfine '/tmp/roc-old check examples/cli/cli-platform/Arg.roc' '/tmp/roc-new check examples/cli/cli-platform/Arg.roc' --warmup 10 Benchmark 1: /tmp/roc-old check examples/cli/cli-platform/Arg.roc Time (mean ± σ): 53.8 ms ± 1.3 ms [User: 87.3 ms, System: 10.8 ms] Range (min … max): 52.2 ms … 60.4 ms 51 runs Benchmark 2: /tmp/roc-new check examples/cli/cli-platform/Arg.roc Time (mean ± σ): 45.0 ms ± 1.6 ms [User: 59.4 ms, System: 11.3 ms] Range (min … max): 42.6 ms … 49.8 ms 60 runs Summary '/tmp/roc-new check examples/cli/cli-platform/Arg.roc' ran 1.20 ± 0.05 times faster than '/tmp/roc-old check examples/cli/cli-platform/Arg.roc' ``` The time spent in `occurs` during checking for `Arg` drops from 50% to 23%. |
