public IntStream stream() {
		return IntStream.range(_min, _max);
	}
Returns a sequential ordered {@code IntStream} from {@link #min()}
(inclusive) to {@link #max()} (exclusive) by an incremental step of
{@code 1}.
<p>
An equivalent sequence of increasing values can be produced sequentially
using a {@code for} loop as follows:
{@snippet lang="java":
for (int i = range.min(); i < range.max(); ++i) {
    // ...
}
}

@since 3.4

@return a sequential {@link IntStream} for the range of {@code int}
        elements
