Meet the Kiboshi clan of Reactula. They are hard to miss and are famous for their anger issues and geeky science experiments.

The Reactive Gods have chosen them to build a spaceship for the epic battle, “The Invasion by Earthlings”. The Kiboshi’s couldn’t have asked for more and killing aliens was on the top of their ‘Things to do before you die’ list. Thus, they start building an epic war machine, a spaceship that could fire at a given constant rate.

Here is the Kiboshi’s first attempt at the warship:

The dream of popping aliens was never so close, but the Reactive Gods are never easy to please, are they?

Stop task on interrupt

The God Of Time, Gogoti doesn’t like wars. He is a sleepy, compassionate guy, who wants his subjects to chill and get drunk as soon as the sun sets. He commands the Kiboshi’s to shut down their war machine when he signals dusk.

And since this is planet Reactula, everything here is a stream. Gogoti promise to hand the Kiboshi’s an observable for the time of the day, which will signal dawn , afternoon or dusk .

The Kiboshi’s are distressed. They’ve built this beautiful spaceship which can fire for eternity. They were so obsessed with the thought of killing the aliens, that the idea to stop firing never crossed their minds. But the Reactive Gods must be pleased, and just before the Kiboshi’s were getting drunk and falling into oblivion, they heard a whisper - takeUntil .

After few drinks and beating up historians, they found the sacred scripture describing takeUntil.

This hint was enough for the Kiboshi’s. They have now changed their spaceship to use takeUntil and as expected, it stops firing at dusk.

Gogoti is pleased, and the Kiboshi’s are back on their mission of killing aliens and living a happy drunk life. The warship they built, has been firing for the whole day without any problem. All of Reactula is celebrating their inevitable victory over the aliens. Glory songs are being written for the Kiboshi’s and they are flooded with marriage offers.

But life on Reactula is unexpected.
