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.

>>171862+(OP)
In rust, handing out indexes isn’t that common. It’s generally bad practice because your program will end up with extra, unnecessary bounds checks. Usually we program rust just the same as in C - get a reference (pointer) to an item inside the array and pass that around. The rust compiler ensures the array isn’t modified or freed while the pointer is held. (Which is helpful, but very inconvenient at times!)
