I'm not sure it needs to even be that complex. If you are using all three classes in the same script, why not simply pass the log object in the constructor? 
my $log = Log::Common->new;
my $foo = Foo::Foo->new('log' => $log);
my $bar = Foo::Bar->new('log' => $log);
my $baz = Foo::Baz->new('log' => $log);

I have used a similar method for sharing database handles amongst several different classes.
