Perl list referencing reversing :   Folks, I am newbie to perl. And have been working with csv's, json's, list and hashes.</br>

**I have written this code, but it is giving me error. I want to use this *$header_copy* in foreach loop.**
 

        1. my @headers=qw/January February March April May June/;
        2. my $header_copy=\@headers;
        3. print("$header_copy->[2]");  # Prints "March" Correctly
        4. print("$header_copy[2]");    #Gives Error.


>>**Error :**
***Global symbol "@header_copy" requires explicit package name at line 4***

And I want to use $header_copy in for loop: like</br>
</br
