This is probably a dumb question. I am trying to take a list of @num_weights and add one number from @leftovers to the front, save it in a @hold_generations array, for all @leftovers. The code is: 
my @num_weights = [36,264,188];
my @leftovers = [1,2,3,4];
my @hold_generations;
 my $i = 0;
        
        for(my $p = 0; $p < 1;$p++) #Go through all leftovers
            {
                my $pick = $leftovers[$p];
                unshift @num_weights, $pick; #add item
                say Dumper(@num_weights);
                push @hold_generations, @num_weights; #store new array
                say Dumper(@hold_generations);
                splice @num_weights, 1, 1; #undo adding item
                say Dumper(@num_weights);
                
                 
            }

However, I am getting this result from Dumper() 
$VAR1 = [
          1,
          2,
          3,
          4
        ];
$VAR2 = [
          36,
          264,
          188
        ];

$VAR1 = [
          1,
          2,
          3,
          4
        ];
$VAR2 = [
          36,
          264,
          188
        ];

$VAR1 = [
          1,
          2,
          3,
          4
        ];

Shouldn't Var1 be 1,36,264,188? That's whay I'm trying to get!

I'm sure there is a better way to do this, but I'd really just like to know whats going on.

My goal is to use bigger data sets and later on check @hold_generations for specific instances and then use that instance to re-run this whole thing.
