That'd be a pretty crappy iterator implementation, short-circuiting is basically what iterators are all about (how else would you handle infinite iterators?). For example, in Rust, it's simply Iterator::find(): https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.find https://doc.rust-lang.org/std/iter/trait.Iterator.html#metho... for loops in Rust are basically just syntax sugar for a while loop taking an element of the iterator each iteration, you can use break/continue as normal.
