Release Notes: The way primitive procedures are defined and invoked was changed. Reflection is not used any more, thus achieving calls that are 30 times faster. Primitives are defined as anonymous classes in arrays of primitives, overriding one of the apply methods.
Release Notes: Starting from this release, it is possible to instantiate and use Java objects from Scheme. An initial Scheme <-> Java type conversion mechanism is implemented. Now Java code can define new Scheme variables holding Java objects. There is a new build.xml file.
Release Notes: Now it is possible to have multiple independent instances of the Gleam interpreter in the same JVM.
