The debatably Free monad

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.

About This Talk

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.

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.
