How about using can? 
    $something->set_call_back( $this->can('func') );

[download]
can returns a subref.

You should use this method if inheritance matters to you, because can respects inheritance; if you directly take a reference to a sub in a package, and that sub is actually an inherited method, you'll have a problem. :) You won't have that problem with can.
