Documentation Bug introduced 2017-07-06 22:41 UTC by Report Bug Copy Issue Report It seems like `new static()` of type `this<Amarkal\Shortcode\Manager>` is incompatible with the declared type `object<Amarkal\Shortcode\Singleton>` of property `$instance`. Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.
