Yeah, that was the idea. Just a language for fun and specifically for code golf (solving programming problems in as small a program as possible). In the case of Retina, it turned out the language is actually pretty useful for throwaway scripts for string manipulation, so I actually am using the language while working occasionally, but that was definitely not a design goal. :D

Exactly. The author is active on the Code Golf Stack Exchange and wrote this programming language with code golding in mind, which is viewed as relaxing by some.
