A Futuristic Eagerload idea for fluent

Fluent3Eagerload.swift

// Per Tanner
let cache = \User.pets.prefetchCache()
let users = User.query(on: ...).filter(...).prefetching(\.pets, into: cache).all() // await
for user in users {
    let pets = user.pets.get(from: cache)
}

// Shaun's idea
struct User: Model {
  var pets: Childeren<User, Pet>?
  var children: Childeren<User, User>?
  var creditCards: Childeren<User, CreditCard>?
}
// Query For Users and Kids, not credit cards those need to be secure
let cacheService = req.make(CacheService.self)
let userQueryBuilder = /// your user query
let user = userQueryBuilder.prefetch(\.pets, \.children, into: cacheService).first().blockingAway()
user.pets // has pets data
user.children //  has child data
user.creditCards // is nil
