Questions tagged [sisc]

SISC is short for Second Interpreter of Scheme Code, in reference to its predecessor LISC, the Lightweight Interpreter of Scheme Code. SISC depends on Sun Microsystems' Java programming language platform. This runtime environment allows SISC to provide many extensions and libraries such as networking, exception handling, a module system, and a Java foreign function interface.

What is the main difference between SRFI 40 (deprecated) and 41?
