in reply to Mini-Tutorial: Dereferencing Syntax
It's also worth noting that the following are two completely different things.
@hash{'key1', 'key2'} $hash{'key1', 'key2'}
The first one is basically a shorthand for:
($hash{'key1'}, $hash{'key2'})
The second one is:
$hash{join($;, 'key1', 'key2')}
... where $; is the subscript separator, which defaults to \034.
