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.
