Creates a lazy-loading ghost instance.

Skipped properties should be indexed by their array-cast identifier, see https://php.net/manual/language.types.array#language.types.array.casting

Parameters

\Closure(static):void $initializer The closure should initialize the object it receives as argument:

array<string, true>|null $skippedProperties An array indexed by the properties to skip, a.k.a. the ones: that the initializer doesn't initialize, if any
