in thread Why was it neccessary to pass a DBI handler by reference?

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.
