Flisp

Flisp is a small lisp dialect. It is currently written in Java. Flisp supports lexical closures, arbitrarily precise arithmetic, and a module system.

Flisp Tutorial:

Hello World

(print "Hello World")

Flisp Data Types

Flisp contains two primary data types: the atom and the list. Lists can contain any Flisp data type. Atoms can be: strings, numbers, or symbols. Numbers are arbitrarily precise.

( ... list contents ... )
