Editor note: This behaviour is due to BC concerns with PHP 7, and will likely be fixed in PHP 9.

PHP 8.3

interface AnyType {}
interface Type2 {}

function test (AnyType|null $param) {}

The ReflectionParameter will return ReflectionNamedType, NOT ReflectionUnionType (null is ignored basically).

However, function test (AnyType|Type2|null $param) {}

will return ReflectionUnionType with 3 types, NOT 2 (null is not ignored this time).

To me, this is just wrong and logical error in PHP.
