gonna do an intro to kotlin presentation at my company. slideware then a coding exercise. curious if anyone has any good coding exercises they’ve found useful for something similiar. something that actually solves a real-ish problem, and is useful for highlighting a good amount of the features that makes kotlin interesting. (something a bit more complicated than the individual kotlin koans)

One suggestion I have is to look through the #feed channel. It's not uncommon for people to post their "here's how problem XYZ became so much easier in Kotlin" stories there

The java interoperability was what convinced me. No need to "refactor the codebase".
