			0 ignored issues – show Documentation introduced 2018-08-23 10:08 UTC by Report Bug Copy Issue Report `array($ast->getType(), $ast->getFullName())` is of type `array<integer,?,{"0":"?","1":"?"}>`, but the function expects a `object<Railt\SDL\Frontend\IR\iterable>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...

However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.
