Think of that as the same as @array[2..2], as in, a list that has
only one element.  "print" prints a single element list in the same
way that it prints a scalar.

But let's put this on the left side of an assignent:

$array[2] = @ARGV; # get the count of arguments into $array[2]
@array[2..2] = @ARGV; # get the first argument ($ARGV[0]) into $array[2]

quite different reactions!
