While on one hand, we have the features of the language itself and the many libraries and applications that were developed over the years, on the other hand, we have a topic we rarely talk about: how Clojure helps in areas where it isn't even there. Is it important to care about the world outside of Clojure? If so, why? And in what ways, how does Clojure and its community inspire others to do great things, even without the use of Clojure itself? In this talk, I would like to tell a little story of a language called Hy, which is a Lisp that compiles to Python AST - a different syntax for Python, with some syntactic sugar, if you wish. The tale would tell how Clojure - the language, the community, the tools and libraries around it - influenced Hy and some of the neat little things written in it.
This would be a cultural exploration, rather than a talk about deep technicalities or methods, although a few interesting - or twisted - bits of the deep internals could be explained, for educational purposes, and for comparing how Clojure accomplishes similar things. The presentation would also touch on the differences, and the "why"s behind them, to answer questions like "why isn't Hy a ClojureScript backend?", because the answers are mostly non-technical, and as such, a good fit into the presentations theme.
