+One thing that we changed from the original `println` definition is that we prefixed the invocations of the `print!` macro with `$crate` too. This ensures that we don't need to have to import the `print!` macro too if we only want to use `println`.
+
+Like in the standard library, we add the `#[macro_export]` attribute to both macros to make them available everywhere in our crate. Note that this places the macros in the root namespace of the crate, so importing them via `use crate::vga_buffer::println` does not work. Instead, we have to do `use crate::println`.

 The `_print` function locks our static `WRITER` and calls the `write_fmt` method on it. This method is from the `Write` trait, we need to import that trait. The additional `unwrap()` at the end panics if printing isn't successful. But since we always return `Ok` in `write_str`, that should not happen.

+Since the macros need to be able to call `_print` from outside of the module, the function needs to be public. However, since we consider this a private implementation detail, we add the [`doc(hidden)` attribute] to hide it from the generated documentation.
