in thread Question about ternary operator

No, it should look exactly like the first statement. The ternary operator is very good if you use its value, but if you use it in void context it's just a kludge for an if statement. So
# bad: ternary in void context: exists($checked->{Group}{$GroupDN}) ? ($rc_OK=1) : ($rc_OK=check_group +($GroupDN,0)); # good: 'if' in void context: if (exists($checked->{Group}{$GroupDN})) { $rc_OK = 1 } else { $rc_OK=check_group($GroupDN,0) } # also good: ternary in scalar context: $rc_OK = exists($checked->{Group}{$GroupDN}) ? 1 : check_group($Group +DN,0)

So you have two good, idiomatic ways to express something, and complain that the third is a PITA?
