Thanks for the pointer, but $count is already used in the while loop below:
while (my ($author, $count) = each %count) {
my $ok;
if ($expect{$author} != $count) {
$bad = 1;
$ok = "bad";
}
else {
$ok = "good";
}
print STDERR "Author $author (expected $expect{$author}, attributed $count) $ok\n";
}
I'll go and change the one in my new while loop though, to use the Perl idiom way you listed below.
