Sebastian Aigner explains Kotlin's rangeUntil operator and how it enables true open-ended ranges without workarounds.

The rangeUntil operator, or is a new way to create open-ended ranges in Kotlin. You might think of this new operator as just an alias for the long-existing “until” function in Kotlin, but that would mean missing out on some powerful new things that weren’t possible before. Let Sebastian Aigner (twitter.com/sebi_io) give you a rundown of these new features, such as the ability to specify OpenEndRanges properly and without any workarounds, in an entirely backwards compatible manner. Find out more details in the KEEP document for open-ended ranges and leave your feedback: github.com/Kotlin/KEEP/blob/open-ended-ranges/proposals/open…
