Discussion

Background

Describe where the project came from. What is the historical journey of the project; who/what company wrote the project. Did it go through any significant alterations/rewrites/language changes?

Golo comes from the research activities of the Dynamid team of the CITI-INRIA Laboratory at INSA-Lyon. After experimentations in the JooFlux dynamic aspect and code injection toolkit, we realized that we could take advantage of the invokedynamic / JSR 292 to design a small, efficient and easy to hack dynamically-typed programming language for the JVM. By "easy to hack", we mean that language and runtime experiments can be approached by students and hobbyists, not just programming language design experts.

We released the first preview of Golo at the Devoxx France conference in March 2013. The language was presented in various JUGs and conferences, including De
