I am trying to get some Perl code to work but can't seem to see my problem. My issue is a variant of the recipe 12.16 in Perl Cookbook.

Specifically, I'm trying to get a reference to a function that might not exist in a Perl package. I know that I can use the Exporter module to probably make this work, but I've invested some time into trying to figure this out and would like to see if I can make it work.

What I have is: 

        eval {
                no strict "refs";

                require "$fqn_file";

                local $SIG{'__DIE__'};
                $ref = \&{$foo . "::f_preferred"};
        };
        warn $@ if $@;

But, I keep getting $ref set to a value even though f_preferred is not defined. What I would like is for it to return "undef" in this case.

Any help is much appreciated..
