This talk is my slightly expanded version of that statement, and should hopefully understand what "Free" is, what purpose it serves and where it came from.
Free is something I've wanted to understand for quite a while, but could never quite figure it out. I’d essentially given up on it until a friend of mine, known to be particularly fond of pithy statements, told me "Free is merely the defunctionalisation of Monad in its most uncomfortable configuration". He didn’t add "what’s the problem?" but it was clearly implied.
The odd thing though is that after playing with this for a bit, it turned out to be exactly what I needed to hear to get me unstuck.

In this talk, we will demonstrate some elegant applications of functional programming in Scala, with even more elegant visual results - all with live code and real-time output.
This talk aims to equip the audience with the minimum required bagage to get comfortable working with contravariance.
Join me in a talk empowering you to build Scala applications that not only excel internally but also deliver optimal experiences from an external perspective.
I propose that we can extend Mirrors to operations, and use the most natural DSL of all - plain trait definitions.
