Just changing to \$dbh will not work without other changes. So the big question is are you sure you just changed the new call and the new method (to properly de-reference the reference to $dbh)? Were there possibly any other changes?

    I made the following changes:
    • call to $one->new sends \$dbh instead of $dbh.
    • One::new expects \$dbh instead of $dbh, and dereferences it.
    That's it. I didn't expect it to work, and only tried it because the symptom seemed to be that of a variable passed by value, not by reference. The fact that it did work has left me bewildered, and is the reason I started this thread.
