There are many ways you can insert data into an array:

• push and unshift let you easily insert at the ends.

• You can also insert at the ends with simple assignment:

  @T = ( 'FIRST', @T, 'LAST' );
• You can also use the aforementioned splice to insert items in the middle of a list.

• Reassigning with slices can also do the trick:

  @T = (@T[0..50], 'FOO', 'BAR', @T[51..$#T]);

• I frequently find myself rebuilding lists into new lists as I process items:

  my @tmp;
  for my $item (@T) {
      if (..insert condition..) {
          push @tmp, 'Scooby Doo!';
      }
  
      if (..keep condition..) {
          push @tmp, $item;
      }
  }
  @T = @tmp;

Which method(s) you choose depend on which is most convenient in the code you're writing.

Notes: None of these have been tested, and the ...blah.. need to be replaced with appropriate expressions.
