Want indexing arrays to not work anymore?

Simply do this:

compile_fail use break_array; let array=[0,1,2,3]; assert_eq!( array[0], 0 ); and marvel at the compiler error: ``text | 6 | assert_eq!( array[0], 0 ); | ^ expected structbreak_array::MyType`, found integer

error: aborting due to previous error

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