----------------------------------------
Feature #16991: Sets: add Set#join
https://bugs.ruby-lang.org/issues/16991#change-100928
* Author: marcandre (Marc-Andre Lafortune)

----------------------------------------
I'd like to add `#join` to `Set`:
```ruby
# Now:
Set[1, 2, 3].join('x') # => NoMethodError
# After
Set[1, 2, 3].join('x') # => "1x2x3"
```
I'd make this join never recursive. (I've never wanted to use the recursivity of
`Array#join`, but it may very well just be my particular experience)
Reminder: Why there is no `Enumerable#join`:
