It looks like you've a singleton 'app' and it's been passed around to invoke methods. Normally this sounds like where DI is used? even thought DI would still require you to write $obj->method. Below idea could work. but I'm not really expert in the magical part of Perl. :) 


sub _get_instance {
   ... init singleton if not created yet.
   return $app;
}
sub log {
# well there should be some easy way to somehow create function that f
+orwards to singleton
   my $app = &_get_instance;
   $app->log(@_);
}
