@ExperimentalStdlibApi operator fun UShort.rangeUntil(
    to: UShort
): UIntRange

Returns a range from this value up to but excluding the specified to value.

If the to value is less than or equal to this value, then the returned range is empty.

@ExperimentalStdlibApi operator fun <T : Comparable<T>> T.rangeUntil(
    that: T
): OpenEndRange<T>

Creates an open-ended range from this Comparable value to the specified that value.

This value needs to be smaller than that value, otherwise the returned range will be empty.
