class AutoSetHook[INSTANCE, BINDING] extends PlanningHook

A hook that will collect all implementations with types that are

_ <: T

into a Set[T] set binding available for summoning

Usage:

val collectCloseables = new AutoSetHook[AutoCloseable, AutoCloseable]

val injector = Injector(new BootstrapModuleDef {
  many[PlanningHook]
    .add(collectCloseables)
})

Then, in any class created from injector:

class App(allCloseables: Set[AutoCloseable]) {
  ...
}

These Auto-Sets can be used to implement custom lifetimes:

val locator = injector.produce(modules)

val closeables = locator.get[Set[AutoCloseable]]
try { locator.get[App].runMain() } finally {
  // reverse closeables list, Auto-Sets preserve order, in the order of *initialization*
  // Therefore resources should closed in the *opposite order*
  // e.g. if C depends on B depends on A, create: A -> B -> C, close: C -> B -> A
  closeables.reverse.foreach(_.close())
}

Auto-Sets are NOT subject to Garbage Collection, they are assembled *after* garbage collection is done, as such they can't contain garbage by construction and they cannot be designated as GC root keys.
