I wouldn't call that careless. So far, proposals to extend the for-loop have not passed the cost/benefit test. I think supporting iterators would require something like magic-methods, which so far are not a thing in Zig (language syntax doesn't interact with userland code).

The status quo for iterators is this:

  var it = getSomeIterable();
  while (it.next()) |item| {
      ...
  }

IMO it's "good but not great" (not great because it adds a var and the variable pollutes the outer scope). But the alternative is a bit of a pandora's box.
