Interesting... You made a little typo, that should be a semicolon on the end of the open() line. But look at this, it seems to solve pg's problem. And interestingly, IO::File has the same behaviour that pg is complaining about. Is this behaviour of $. a bug or a feature?
#!/usr/bin/perl
my $file = "pg-write3";
{
open my $fh, $file or die "open: $!";
$line = <$fh>;
$line = <$fh>;
print "two reads:\t$.\n";
}
# $fh is closed here
print "closed file:\t$.\n";
{
open my $fh, $file or die "open: $!";
print "open again:\t$.\n";
$line = <$fh>;
print "one read:\t$.\n";
}
# $fh is closed here
print "closed again:\t$.\n";
__END__
Output:
two reads: 2
closed file: 2
open again: 0
one read: 1
closed again: 1
