I've made a new version which filters out duplicate callbacks:

    http://occamstoothbrush.com/downloads/perl/CGI-Application-4.0_3-positionless-class-callbacks-patch2.tar.gz

Basically call_hook now keeps a hash of callbacks that it has already 
executed for the current hook.  If it encounters the same hook more than
once, it runs it the first time and skips it thereafter.

There's also a small change to the test script to test for this.
