Storing Objects in a Session

[jonathan vanasco]

slightly OT, but i'm doing this in mod_perl!
server
        Apache/2.0.52 (Unix)
        mod_perl/1.99_16
        Perl/v5.8.1
use
        use Apache::Cookie;
        use Apache::Request ();
        use Apache::Session;
        use Apache::Session::File;
is there any way to store an object into an Apache Session ?
all attempts have been fruitless.  i'd rather not rebuild the object by 
hand each time, but if needed i will.
