    Oops, you're right. Array is totally wrong. Making the change to the original post!
      How about $x{@y} then? How does that work?

      For instance, in a foreach $x(@y){} line of code.

        How about $x{@y} then? How does that work ... in a foreach $x(@y){} line of code.

        There is no  $x{@y} expression in the
            foreach $x(@y){}
        statement. In that statement,  $x is aliased to successive elements of the  @y array on each execution of the loop.
