fun <T> Iterator<T>.asSequence(): Sequence<T>
fun <T> Iterator<T>.asSequence(): Sequence<T>
fun <T> Iterator<T>.asSequence(): Sequence<T>

inline fun <T> Iterator<T>.forEach(operation: (T) -> Unit)
inline fun <T> Iterator<T>.forEach(operation: (T) -> Unit)
inline fun <T> Iterator<T>.forEach(operation: (T) -> Unit)
inline fun <T> Iterator<T>.forEach(operation: (T) -> Unit)

Performs the given operation on each element of this Iterator.

inline operator fun <T> Iterator<T>.iterator(): Iterator<T>
inline operator fun <T> Iterator<T>.iterator(): Iterator<T>
inline operator fun <T> Iterator<T>.iterator(): Iterator<T>

Returns the given iterator itself. This allows to use an instance of iterator in a for loop.
