The simplest is probably:

foreach my $v1 (@array1)
  { my $v2= shift @array2;
    print $v1, $v2;
  }

Of course this relies on @array1 and @array2 having the same number of elements!

If the arrays can have different sizes then you can do:

# print all elements
while( @array1 || @array2)
  { my $v1= shift @array1 || "empty"; # or whatever default value
    my $v2= shift @array2 || "empty";
    print $v1, $v2;
  }

# print elements up to the shortest array length
while( @array1 && @array2)
  { my $v1= shift @array1;
    my $v2= shift @array2;
    print $v1, $v2;
  }

I can't wait to see the golf versions!
