Again, I do not see the point of module_call if you can do:

if (drupal_function_exists('cool_function')) {
  $mymod_bar = cool_function($args);
}

Advantages?
- It is cleaner and faster
- It does not add a new level of indirection
- It makes reference tracking works (such as what is done on api.drupal.org)

Moreover, you can do correct error management:

if (drupal_function_exists()) {
}
else {
}
