require_so: DRYer StackOverflow copying

Today I was reading a post on the StackOverflow blog when I was struck by this passage:

Code cloning, you say? In my DRY Ruby codebase? Not if I can help it!

And so I got to work. After extensive research, I concluded that deleting the snippet from StackOverflow to make my version the canonical one was not a viable option.

So I flipped the problem on its head: why not make the StackOverflow version the canonical one? And thus, require_so was born.

Locate the code snippet

Copy the short permalink below the StackOverflow answer

Paste it into your code

And voilà, the methods defined in the snippet will be brought into scope.

No more code cloning!
