The range operator is kind of primitive.splain

Range iterator outside integer range (#1)
    (F) One (or both) of the numeric arguments to the range operator "
+.."
    are outside the range which can be represented by integers interna
+lly.
    One possible workaround is to force Perl to use magical string inc
+rement
    by prepending "0" to your numbers.

You can always range :) 
sub range {
  my( $start, $end ) = @_;
  my @ret;
  while($start <= $end ){
    push @ret, $start;
    $start++;
  }
  return @ret;
}

use bignum;
my $x = 2**1024
for(range( $x , $x+2 )) {
  say
}
