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.

Funny, it's really the same thing, why Rust people say we should abandon C. Meanwhile in C, it is also common to hand out handle instead of indices precisely due to this problem.

		It's pretty similar, but writing `for item in container { item.do_it() }` is a lot less error prone than the C equivalent. The ha-ha-but-serious take is that once you get that snippet to compile, there's almost nothing you could ever do to break it without also making the compiler scream at you.
