Not only is it convenient, it also enables parallelism:

“How to Think about Parallel Programming: Not!” - Guy L. Steele Jr. (Strange Loop 2010)

You can choose a custom donation and make most of your money go to the EFF. Then the top tier is just like a €24 donation to the EFF and you only really “pay” €10.30 for the actual books.

Also, I think the ‘find’ operation could be replaced by an operation that checks if two elements are in the same set. That way you don’t have to come up with a “name”.

One thing I’m missing is which problems this technique can solve. I believe one important use case is in type inference. Are there many other problems that can be solved by union-find?
