Refal (Recursive functions algorithmic language) "is functional programming language oriented toward symbol manipulation", including "string processing, translation, [and] artificial intelligence". It is one of the oldest members of this family, first conceived in 1966 as a theoretical tool with the first implementation appearing in 1968. Refal was intended to combine mathematical simplicity with practicality for writing large and sophisticated programs. Read more on Wikipedia...
