Alternative go-github API

go-github-client.go

func main() {

  watchers, pager, _, err := client.Activity.ListWatchers("o", "r")
  if pager.HasNext() {
    watchers, pager, _, err = pager.Next()
  }
  //..
  //or:
  watchers, pager, _, err = pager.Last()
}

Infact, the iter.JumpTo could look something like this:

func (i *Iterator ) JumpTo(pg interface{}) {
   // Use stringer
}

okay, but what does func (i *Iterator) Data() return? What I'm getting at, is that I suspect the only thing that would really work is to return interface{}, which requires that the user then type switch to whatever the real type is and you lose all type safety.

One alternative would be to have a new Iterator type for every data type you need to page through, so that Data() can return an exact type rather than iterator{}, but now you've close to doubled the number of types that users of the library have to contend with.

Drats. Its times like these that I feel really really stupid.

I clearly didn't think this through and wasted your time as well.
Although I would blame excessive usage of dynamically typed languages for this stupid suggestion :P

Thanks for your time! And thanks for merging the PR!

No worries... it's not stupid at all. I'm still getting used to working in Go myself... some things really are different here than how you would approach them in other languages (particularly dynamically typed languages, as you mention).

And to be clear, I have no problem with adding something to the library that makes working with paginated results a little easier. I just honestly don't know what else we can do than what we currently have.
