// XXX This pattern is under development. Do not add more callsites
// using this package for now. See:
// https://meteor.hackpad.com/Design-proposal-Hooks-YxvgEW06q6f
//
// Encapsulates the pattern of registering callbacks on a hook.
//
// The `each` method of the hook calls its iterator function argument
// with each registered callback. This allows the hook to
// conditionally decide not to call the callback (if, for example, the
// observed object has been closed or terminated).
//
// By default, callbacks are bound with `Meteor.bindEnvironment`, so they will be
// called with the Meteor environment of the calling code that
// registered the callback. Override by passing { bindEnvironment: false }
// to the constructor.
//
// Registering a callback returns an object with a single `stop`
// method which unregisters the callback.
//
// The code is careful to allow a callback to be safely unregistered
// while the callbacks are being iterated over.
//
// If the hook is configured with the `exceptionHandler` option, the
// handler will be called if a called callback throws an exception.
// By default (if the exception handler doesn't itself throw an
// exception, or if the iterator function doesn't return a falsy value
// to terminate the calling of callbacks), the remaining callbacks
// will still be called.
//
// Alternatively, the `debugPrintExceptions` option can be specified
// as string describing the callback. On an exception the string and
// the exception will be printed to the console log with
// `Meteor._debug`, and the exception otherwise ignored.
//
// If an exception handler isn't specified, exceptions thrown in the
// callback will propagate up to the iterator function, and will
// terminate calling the remaining callbacks if not caught.
