What's the usage of before and afterSave as arguments in save method?

[igorsantos07]

I was wondering if there's any difference between:

1. running code, calling save inside an if-clause and running more code after
2. running save with before and afterSave closures as arguments

The number 2 looks more like a non-standard way to add hooks that are hardly (IMHO) different between situations where save() would be called. Thus, we could drop those arguments in favor of a cleaner codebase and less confusion (since now with actual, instance before/afterSave methods, both signatures are different and one does not override the other anymore).
