Hi, is there a way to generate a new array with the common elements in
array A and arra B? This is:
arrayA = ["qqq", "www", "eee"]
arrayB = ["www", "eee", "rrr", "ttt"]
the result should be: ["www", "eee"]
Thanks a lot.

Of course I mean a method which perhaps I miss in Array class. If not,
I can do it manually

arrayA | arrayB should do the trick

That would be the union. He's looking for Array#&
