Lexicon has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to use Apache::Session, which returns the session as a tied hash. I'd like to impliment, for example, a Logout(%SESSION) subroutine whereby I delete (read, untie) the session. The ultimate question is do I have to retie the hash tie %SESSION, 'Apache::Session::MySQL' inside the subroutine, or is there some way to pass a reference to the object so that I can call tied(%SESSION)->destroy right off?

My impression from Programming Perl and perldoc is I'll have to retie the %SESSION every time the has is passed, which seems unpleasant in a number of ways.

    If you are just passing around a reference to a tied hash, there is no need to retie it.
