Err... they look rather similar, don't they? :P
Basically, it works a little like:
my %hash = ( "key1" => "value1",
"key2" => "value2",
"key3" => "value3"
);
print $hash{key1};
where:
$hash is the name of the hash (obviously),
key1 is a key to pointing to a value in the hash, and
$hash{key1} is the value associated with that key.
When you see:
$hash{$key}
you really mean:
Return the value associated with a key ($key) held in a
variable; from the hash called %hash.
