is there any way to pass an Iterator into another function during a loop, as in: // iter: &mut impl Iterator for _ in iter { // ... some_fn(iter); // ... }

why are these different? I'd thought for-loops were sugar for the while-let form
They almost are. For loops are equivalent to let mut unnamable_variable = iter.into_iter(); // this took ownership of iter while let Some(_) = unnamable_variable.next() { ... }
