  1. Would you try deleting the if about Coalesce in TypeSpecifier on line 971 to see if it's still needed?
  2. Shouldn't this somehow work recursively even for $foo ?? $bar ?? $baz?

  1. Shouldn't this somehow work recursively even for $foo ?? $bar ?? $baz?

Without thinking too much about it it might, but I'd rather approach that separately - I haven't seen that kind of type narrowing in actual code before.

The test failure is unrelated as far as I can tell - broken by laravel/framework@d44c345
