About SISC
----------
SISC is an extensible heap-based interpreter of Scheme running on
the Java VM, with an aggressively optimized, lightweight (<200k)
Scheme engine. SISC outperforms all existing Java
interpreters (often by more than an order of magnitude), and is
competitive with interpreters in any language.
In addition, SISC is a complete implementation of the language.
The entire R5RS Scheme standard is supported, without exception.
This includes a full number tower including complex number support,
arbitrary precision integers and floating point numbers, as well as
hygienic R5RS macros, proper tail recursion, and first-class
serializable continuations (not just the escaping continuations as
in many limited Scheme systems). SISC also attempts to implement the
standard as correctly as possible, while still providing
exceptional performance.
Finally, SISC provides many useful real-world extensions, such as
networking, threading, elegant exception handling, generic
procedures, an object system, SLIB and comprehensive SRFI support, a
scope-friendly module system, a Scheme and Java object system
with a clean foreign-function interface and more.
