Golo (programming language)
Golo is a simple, dynamic, weakly-typed language for the JVM created in 2012 as part of the research activities of the DynaMid group of the Centre of Innovation in Telecommunications and Integration of service aka CITI Laboratory at INSA Lyon.
History
It has been build as a showcase on how to build a language runtime with invokedynamic. Golo is largely interoperable with Java and other JVM languages (e.g., numeric types are boxing classes from java.lang, and collection literals leverage java.util classes).
In June 2015, Golo became an official Eclipse Foundation project.
Technical Details
The language features have been initially designed around the abilities of invokedynamic / JSR 292 that appeared in Java SE 7. Golo uses ahead-of-time compilation of bytecode. While the bytecode remains stable over a program execution, the invokedynamic-based reconfigurable call sites support the adaptive dispatch mechanisms put in place for helping the HotSpot JIT to extract reasonable performance.
