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.
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.
