About:
SISC is an extensible Java-based interpreter of the algorithmic language
Scheme. It uses modern interpretation techniques and handily outperforms
all existing Java 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. This includes a full number tower
including complex number support and arbitrary precision integers and
floating point numbers, proper tail recursion, hygienic macros, and full
support for first-class continuations (not just the escaping continuations
found in many other systems). 

Changes:
A new I/O layer that is 10-30x faster. A new custom I/O ports API. Better
Java and Scheme I/O integration.
