There really should be a `#[cfg(debug)]` currently you can define something like `#[cfg(feature= "debug")]` but you than have to manually add `--features debug` to your `cargo build`.

On the other hand, I can see why you would want an explicit call.

edit: hihi, I misjudged the age of this thread, reading "Apr'15" I though this was only 3 days old 😛
