Since there is already a mix of predicates within the query (for sub objects) they should have unified the syntax. Something like:

user {

    id: 3500401,

    name,

    isViewerFriend,

    profilePicture  {

      size= 50,

      uri,

      width,

      height

    }

  }

As shown you could use a different indicator for filter properties that should not be included in the serialized object graph.

Yeah, it's odd. It's not clear why they're just not using json... json will give you an homoiconic language of arbitrary descriptive power.
