This talk will be a quick introduction to the Unison "paradigm" and language, from the perspective of a long-standing Scala programmer.
In this talk, we'll cover the essentials of macros, why they are useful, why you should care about them, and how to become as good as you need with them for practical purposes.
In this talk, I'll look at the different uses to which tagless final is put to, and see what we can learn about when it is useful and when it just gets in the way.
During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.
