Julien Ponge, who, in addition to being a Java developer and a professor, also writes technical articles for both otn/java and Java Magazine, has created Golo, a simple, dynamic, weakly-typed open source language that favors the explicit over the implicit. Developers can pick it up in a manner of hours, not days. Responses to its recent release at Devoxx have been favorable.
Built from day 1 with invokedynamic, and currently in beta, Golo takes advantage of the latest advances of the JVM. It is also a showcase on how to build a language runtime with invokedynamic.
The Golo Programming Guide is located here.
Julien is an Associate Professor (Maître de Conférences) in Computer Science and Engineering at INSA-Lyon in France, plus an R&D Computer Scientist at the CITI / INRIA laboratory. Learn more about him here.
