Duby is a customizable programming language featuring static types, local type inference and a heavily Ruby-inspired syntax. Duby currently includes a typer/compiler backend for the JVM which can output either JVM bytecode or Java source files.

The Ruby2Java compiler inspects the *runtime* definition of classes to produce a normal-looking Java class. All metaprogrammed methods are reflected on the Java class, as are runtime modifications to those methods.
