First let me make sure I understand your question correctly, since it is not very clear what exactly you are looking for.( Posting some code would have helped.)

You have code of the type

use strict;
use warnings;
use vars( @list0, @list1, @list2 );

sub DoSomething()
{
    my( @localList0, @localList1, @localList2);
    #do something here

    my( @tempList ) = ( \@localList0, \@localList1, 
                        \@localList2 );
    return @tempList;
}

#main program
my @tempList = DoSomething();
push @list0, @$tempList[0];
push @list1, @$tempList[1];
push @list2, @$tempList[2];

Assuming above (or something similar) is what you are looking at improving, I would suggest passing in references to the array into the subroutine. The subroutine can then push stuff onto the right arrays without the need of temporary arrays. 

use strict;
use warnings;
use vars( @list0, @list1, @list2 );

sub DoSomething( \@ \@ \@ )
{
    my( $listRef0, $listRef1, $listRef2) = @_;
    #do something here
 
    push @$listRef0, somelist;
    push @$listRef1, somelist;
    push @$listRef2, somelist;
}

#main program
DoSomething( \list0, \list1, \list2 );

The other, less preferred option would be to directly refer to the outer arrays from within the subroutine. Depending on the size of your program this might be clearer, especially if your script needs to be maintained by someone not familiar with perl style references. However, if the subroutine will be in a separate module, you want to avoid doing this at all costs. 
use strict;
use warnings;
use vars( @list0, @list1, @list2 );

sub DoSomething()
{
    #do something here
 
    push @list0, somelist;
    push @list1, somelist;
    push @list2, somelist;
}

#main program
DoSomething();
