The hash $vars points to has a key named "key2".
: $vars = {
: xxx => "AAA",
: yyy => "BBB",
: zzz => "CCC",
: };
Now you change the reference stored in $var. It points to an entirely
new hash, whose keys are "xxx", "yyy" and "zzz".
: $vars->{'key1'} = "value of first key";
Here you add the key "key1" to the hash $vars points to.
: Problem is, that value of key2 is lost after I set values to xxx, yyy and
: zzz, but key1 is ok.
$vars contains a reference to a hash that has nothing to do with the
first one, you didn't create a key named "key2" in that hash.
