JLambda is a fast, efficient, minimalistic, call-by-value,
lexically scoped Lisp or Scheme like language with closures.
It is implemented in, has exactly the same underlying primitive
data types as Java, and access to all of Java's built in packages and
classes, as well as any other Java classes found in the class path.
It is an essential component of SRI's Pathway Logic project, and
comes as part of the IOP framework distribution (qua iop.jar, currently
weighing in at 1.2M).
