No. I am not looking for one more Try Catch module.
I am looking for possibility to catch errors rised up in Mojolicious::Routes::_dispatch_controller method in 415 .. 419 lines. Here are those lines:

      # Call action
      if($app->can($method)) {
        $stash->{'mojo.routed'} = 1 unless $staging;
        $continue = $app->dispatch($method);                # XXX: changes !!!!!!!!!!!
        #$continue = $app->$method;                         # Original.
      }
I have to wrap $app->$method call by "dispatch" function to catch error that rise up in the $method body.
So the "dispatch" wrapper used to catch errors rised during the $method execution.

I do not want to perform idiotic job wrapping every controller function body to catch errors.
I want to have centrilized try catch decision.
So I want to catch errors rised up in the controller before they catched by this block:

# Controller error
  unless ($success) {
    my $e = Mojo::Exception->new($@);
    $c->app->log->error($e);
    $app->render_exception($e) if $app->can('render_exception');
    return $e;
  }
   May be it would be better to give to developers possibility to set the Exception class in MyApp.pm
In that case  "# Controller error" block will look like:

# Controller error
  unless ($success) {
    my $excaptionPackage = $c->app->exceptionCLassName;
    my $e = $ExceptionPackage->new($@);
    $c->app->log->error($e);
    $app->render_exception($e) if $app->can('render_exception');
    return $e;
  }
