I think that's a bit "advanced" or "tricky", and not something you should imitate just now. Get used to dealing with $$name{key} and $name->{key} syntax, as that is present everywhere in modern Perl.

Using a localized package variable instead of a true lexical variable will lose the benefit of lexical variables: if the function calls another function that uses the package variable, it will see the current local-ized use of it.
