Equivalent of array join() for Set in Ruby?

Question

Is there an equivalent of array join() for the Set class in Ruby? or best to just monkey patch my own on the Set class?

Answer 1

What is wrong with set.to_a.join?

Something to keep in mind: The documentation says that a "Set implements a collection of unordered values with no duplicates." That means the order is not guaranteed. For the to_a method the documentation tells you that "the order of elements is uncertain".

I am not sure if a join makes sense with this circumstances...
