proper tail recursion In computer science, a tail call is a subroutine call performed as the final action of a procedure. If the target of a tail is the same subroutine, the subroutine is said to be tail recursive, which is a special case of direct recursion (computer s ...

, and first class continuations. SISC is short for Second Interpreter of Scheme Code, in reference to its predecessor LISC, the Lightweight Interpreter of Scheme Code.{{cite web, url=http://sisc-scheme.org/manual/html/ch01.html, work=SISC for Seasoned Schemers, title=Introduction, author=Scott G. Miller, author2=Matthias Radestock , quote=SISC as a project began as the successor to the Lightweight Interpreter of Scheme Code (LISC). LISC was a small, stack-based almost R4RS compliant Scheme. SISC was born out of the desire to create an interpreter that was of a similar footprint to LISC, but which executed Scheme code much faster, complied fully to the R5RS standard, and which wasn't limited by the stack-based model. SISC met these goals very quickly, and has since progressed in active development to be a competitive Scheme system. As a successor to LISC the interpreter was named the Second Interpreter of Scheme Code., accessdate=2007-09-25 SISC is free software,

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.
