for(1,2,3,4,5)

    $.= $_;

#### prints as expected
2 3 4 5

my $x=1;
for(1,2,3,4,5) 
{
    $.= $_;
  next  if $x..$x; # never returns true!
  print "$_\n";
}
#### prints nothing. Why??? It doesn't test against $. and it doesn't just test the value $x


my $x = 1;
my $y = 0;
for(1,2,3,4,5) 
{
    $.= $_;
  next  if $x..$y; # never returns true!
  print "$_ ";
}
#### prints nothing as well. If the flip and the flop happened at the same round it would have printed something
