Neko
Neko is a lightweight, high-level virtual machine and programming language, created by Nicolas Cannasse in 2005. Initially developed as a target language for Haxe, Neko has since evolved into a versatile tool for scripting, rapid prototyping, and embedding within other applications. It was designed to be simple and efficient, making it ideal for small programs or extensions where more extensive languages like C or Java might be overkill.
Icon
Icon is a high-level programming language developed by Ralph Griswold in 1977 at the University of Arizona. Icon was designed as a descendant of SNOBOL, a language focused on string processing, and aimed to provide more robust and versatile capabilities for handling strings, text processing, and non-numeric data. Its focus is primarily on high-level programming, with strong features for pattern matching, goal-directed evaluation, and implicit backtracking.
