Lib.rs

Want indexing arrays to not work anymore?

Simply create a crate that depends on break_array:

use break_array as _;
fn main(){
    let array=[0,1,2,3];
    assert_eq!( array[0], 0 );
}

and marvel at the compiler error:

  |
6 |     assert_eq!( array[0], 0 );
  |                       ^ expected struct `break_array::MyType`, found integer

error: aborting due to previous error

For more information about this error, try `rustc --explain E0308`.

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