Kotlin largely inherits Java's exception mechanism, but exceptions and functional programming are uneasy bedfellows, leading to most projects adopting "a wing and a-prayer" as their error handling strategy.

I needn’t be so ad-hoc though. In this session we compare and contrast different techniques for handling errors in Kotlin programs. We will discuss the sweet spots, pitfalls and trade-offs encountered in each technique, illustrated with examples from real projects.
