delete entry notation

Before I saw the way Kenneth Love typed delete entry 

entry.delete_instance()

I tried

Entry.delete_instance(entry)

It seem to work! Are they the same?

Your method, i.e. Entry.delete_instance(entry) is better in terms of the hierarchical consistency..

They can be the same. I haven't been able to dig out the code for the Entry class so I won't say for sure that they are the same. But they could be. If you think about it "entry" is an instance of the Entry class. So entry.delete_instance() is just calling the delete_instance method on that particular instance of the Entry class while Entry.delete_instance(entry) is going back to the class itself, calling the delete_instance method, and passing in the entry as the thing to be deleted. Depending on how that method is written (and as I said I haven't pulled out the code so I don't know for sure) these two things can indeed result in the same behavior.
