You literally showed that "for each type of paged object, you write <multiple lines of entirely unnecessary code>".

Where with generics you just have a single generic function.

The problem is: there's no hand-waving in reality.

I'm traveling, so can't properly expand on what I said, but without generics the choice was:

- repeat unnecessary bolierplate code for every single return type

- skip types completely and use a function that accepts interface{} as a parameter and assigns whatever to that variable

Neither are really acceptable in my opinion. And both will be greatly simplified and improved by generics.
