If the programming language has any web presence at all, it will quickly bury the game. Also, it's not like people are going to overhear the word "nim" completely out of context and then google it. If you know it's a programming language, it will be easy to find resources.
Given the long mathematical heritage of the game (check out its Google presence: https://www.google.com/search?q=Nim), I'm not sure that I believe that it'll be so easily upset. On the other hand, the first page of results for https://www.google.com/search?q=Ruby (except the image results) are all about the language, not the gem, so I could be wrong!
