Gosu
'''Gosu''' is a statically-typed runs on vm::JVM-based general purpose programming language that is designed to be expressive, easy-to-read, and high performing. Gosu is uniquely both a high-functioning general purpose language as well as a powerful and concise scripting language. In addition Gosu's type system defines an open API for domain-specific types as opposed to grammar e.g., XSD/XML is type-safe and modeled directly from XML schema files, without intermediate code generation. Gosu began in 2002 from Guidewire Software as an internal language and was released in 2010 to the opensource world. Scott McKinney is the creator and principle developer of the language.
