In `@src/Type/DetectFirstValueTypeCollection.php`:
- Line 29: Update the constructor contract and handling in
DetectFirstValueTypeCollection so Traversable inputs are either explicitly
supported by preserving and inspecting their first yielded item, or excluded
from the `@phpstan-param` annotation if they cannot be handled correctly. Ensure
getType() reports the first item’s type rather than the Traversable
implementation class, while retaining existing array and Arrayy behavior.
In `@tests/PHPStan/GetDynamicMethodReturnTypeExtensionTest.php`:
- Around line 96-111: Rewrite
testFallbackTypeHandlesMissingNeverAndConcreteDefaults to exercise the fallback
scenarios through the public getTypeFromMethodCall() entry point using the
existing supported method-call inputs. Remove the ReflectionMethod construction
and direct getFallbackType() invocations, while preserving assertions for
missing fallback, NeverType, and the concrete “Guest” fallback result.

Handle Traversable inputs before broadening this contract.
mixed makes generators and iterators valid for this constructor, but the fallback wraps a non-array/non-Arrayy value as one element. A Traversable is then stored as an iterator object and getType() returns that class instead of the first yielded value, unlike collections backed by actual item lists.
Add a Traversable branch that preserves and inspects its first item, or keep the PHPStan annotation restricted to inputs this constructor handles correctly.

PHP 8 reflection invoke private method setAccessible true documentation
💡 Result:
In PHP 8, specifically beginning with PHP 8.1.0, the ReflectionMethod::setAccessible(true) method is no longer necessary to invoke private or protected methods [1][2][3]. As of PHP 8.1.0, all methods are invokable by default when using the Reflection API [1][4]. Consequently, calling setAccessible() has no effect [1][5][4]. Furthermore, as of PHP 8.5.0, this method has been officially marked as deprecated [1][5]. You can invoke a private method directly using the standard invoke() method: php class MyClass { private function foo() { return 'bar'; } } $method = new ReflectionMethod("MyClass", "foo"); // No setAccessible(true) needed in PHP 8.1+ $obj = new MyClass(); echo $method->invoke($obj); // Outputs: bar While you may still encounter older documentation or legacy codebases suggesting the use of setAccessible(true), it is technically redundant in any environment running PHP 8.1 or later [1][2][3].

Don’t invoke getFallbackType() through reflection in this test.
getFallbackType() is a private helper, and this test currently exercises it by bypassing visibility rules via ReflectionMethod::invoke(). Cover the same fallback behavior through getTypeFromMethodCall() with the supported extension inputs instead.
