If you read the discussion on std's new dbg! macro,
you'll find that there are good reasons why it shouldn't affect release builds.
As a silent protest against the decision, I made my own version.
```rust use sensible_dbg::dbg;
fn factorial(n: u32) -> u32 { if dbg!(n <= 1) { dbg!(1) } else { dbg!(n * factorial(n - 1)) } } ```
