sisc - 1.16.6-1.1 main

SISC is an extensible Java based interpreter of the algorithmic language
Scheme. SISC uses modern interpretation techniques, and handily outperforms
all existing JVM interpreters (often by more than an order of magnitude).
.
In addition, SISC is a complete implementation of the language. The entire
R5RS Scheme standard is supported, no exceptions. This includes a full number
tower including complex number support, arbitrary precision integers and
floating point numbers, as well as hygenic R5RS macros, proper tail
recursion, and first-class 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.
.
SISC also provides useful real-world extensions, such as networking, elegant
exception handling, a scope-friendly module system, support for SLIB,
numerous SRFIs, and a Java foreign-function interface.
