Want indexing arrays to not work anymore?
Simply create a crate that depends on `break_array`:
```compile_fail
use break_array as _;
fn main(){
}
```
and marvel at the compiler error:
```text

error: aborting due to previous error

Note: You might not be able to get this compiler error if you're from the far future.
