@param-immediately-invoked-callable@throws (PHPStan throws.void when the caller claims
to throw nothing).
By-ref narrowing is not this tag's job: PHPStan still infers
'Ada'|null after a callback that assigns through a reference,
whether or not the callable is immediately invoked.

* Cross-tool handling of `@param-immediately-invoked-callable`.

* Object methods default to later-invoked. The tag overrides a method

* statement. That makes exceptions thrown inside the callback part of
* the caller's `@throws` (PHPStan `throws.void` when the caller claims
* to throw nothing).
*
* By-ref narrowing is not this tag's job: PHPStan still infers
* `'Ada'|null` after a callback that assigns through a reference,
