    with keys. Or do you mean something else? If yes, what?

      I have an array with some values. I want to make elements
      of an array as keys of hash. For this, ideal
      process is that loop through an array and insert array
      elements into keys of hash one by one.
      Is it possible to make this in one line ( i mean w/o loop)?

        Yes, it is possible: 
        my %hash;
@hash{@array} = ();

        This will make your list unique since a hash cannot have duplicate keys.
