Description
Although recursion isn't bad in and of itself, it can often lead to infinite loops. Also some companies don't allow their programmers to use recursion (See this well known paper by NASA).
Jonathan Blow implemented a similar lint for his new programming language in this video.
This lint should probably be allow by default, because in most cases recursion is fine to use.
