fragment merging

[micimize]

I've handled regular field merging

{
      f: friends {
        name
      }
      f: friends {
        id
      }
}
#=>
{
      f: friends {
        name
        id
      }
}

But nested field fragment merging is a nightmare. I'm not going to do it anytime soon.

Basically, figuring out that ...info generates Relationships which contains the field friends which gets merged into friends in the top level query is just a horrible thing to deal with in the current design.

fragment home on Human {
  home: homePlanet
  planet: homePlanet
}

fragment dimensions on Human {
  height
  mass
}

fragment relationships on Human {
  friends {
    name
  }
  starships {
    name
    length
  }
}

fragment info on Human {
  ...dimensions
  ...home
}

query HeroForEpisode($ep: Episode!) {
  hero(episode: $ep) {
    # without typename we can't really tell which fragments to parse
    __typename
    name
    ... on Droid {
      primaryFunction
    }
    ... on Human {
      friends {
        name
        id
      }
      appearsIn
      ...info
      ...relationships
    }
  }
}
