Issue #15198 has been updated by c4am95 (Travis Hunter).
It also seems like it comes up fairly commonly on stackoverflow/blogs:

Feature #15198: Array#intersect?

----------------------------------------
I frequently find myself needing to determine if two arrays intersect but not actually caring about the intersection, so I write code like:
~~~ ruby
(a1 & a2).any?
~~~
It would be nice to have an **intersect?** convenience method on **Array** to perform this query.
