 ## Performance
 It's pretty fast and scales well. In my case, it usually runs in under 0.1ms. The biggest performance hit is functions like `log()`. `log(12345)` evaluates in 0.12ms, and `log(e)` in 0.25ms.
 
-To see how fast it is, you can pass the `--debug` flag in CLI, or the `debug` argument to `eval()`.
+To see how fast it is, you can pass the `--verbose` flag in CLI, or the `verbose` argument to `eval()`.
