----------------------------------------
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.
