Here is an OLD example of short-circuited presedence issues:

ok I understand, but I don't know why my line doesn't work. I thought
(exp) ? (true) : (false)
m} = 1;
: }
: }
:
: this is quite simple, so I rewrite that as:
:
: foreach my $item (@list) {
: chomp($item);
: $seen{$item} ? $seen{$item}++ : $seen{$item} = 1; }
:
: and perl says:
:
: Can't modify postincrement (++) in scalar assignment ...
:
: What I am doing bad?
$seen{$it
(@list) {
chomp($item);
$seen{$item} ? $seen{$item}++ : $seen{$item} = 1;
}
and perl says:
Can't modify postincrement (++) in scalar assignment ...
What I am doing bad ?
