Hi
I have two questions
1) I found this line of code in a book
foreach $item ( @{ $rss->{ 'items'} })
{
print $item->{'title'}
}
I cant quite figure out what the @{ blah } is doing to a hash
reference,
2) I have seen a lot of perl code like $xx = shift;
What does this mean ? what purpose does that server ?
I shall appreciate any answers.
