in thread dereferencing syntax question

Returning a hashref is a lot more efficient than a hash, because of all the flattening Perl does to the hash when passing one back from a subroutine. In a CGI program, a method like param() could be used a lot, so it's important to optimize it.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

    That's why I said I would change it to return a list in *list context*. Returning a hashref may be more efficient, but if you flatten it to a list right after returning it, you've lost most of your gain.
