If you've ever been bitten by a completely unexpected RuntimeException then you've been affected by Hope-Driven Development. If you've ever had to trawl through the source code of the function that you're calling in order to work out what might happen when you call that function, then you'll realise the value of being able to trust a piece of code to do exactly what it says it will do. You would like to know that the code that you call is simple to understand without having to understand the internal workings, and that it will work exactly as expected,*

In this talk, you will discover the problems with existing approaches and how you might improve upon them. Practically you will learn how you might make some major or minor changes to your codebase to make it easier to maintain through greater clarity and composability.
