Indexing into arrays and vectors is really wise to avoid.

The same day Cloudflare had its unwrap fiasco, I found a bug in my code because of a slice that in certain cases went past the end of a vector. Switched it to use iterators and will definitely be more careful with slices and array indexes in the future.

Was it a fiasco? Really? The rust unwrap call is the equivalent to C code like this:

    int result = foo(…);
    assert(result >= 0);

If that assert tripped, would you blame the assert? Of course not. Or blame C? No. If that assert tripped, it’s doing its job by telling you there’s a problem in the call to foo().

You can write buggy code in rust just like you can in any other language.
