// IgnoreInterfaces returns an Option that ignores all values or references of
// values assignable to certain interface types. These interfaces are specified
// by passing in an anonymous struct with the interface types embedded in it.
// For example, to ignore sync.Locker, pass in struct{sync.Locker}{}.
