Issue #15198 has been updated by marcandre (Marc-Andre Lafortune).
Assignee set to matz (Yukihiro Matsumoto)
I am positive on the feature as has valid use cases, it can be optimized in C and as a bonus adds no cognitive load.
I believe we just need a final "yay" from Matz. I'll add it to the next meeting's agenda.

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.
