I’d also argue for the inverse more than this, though. I’d like for my attributes to be validated during compilation instead of delayed to runtime -- which, it isn’t actually. Runtime validation ONLY happens when calling ->newInstance() on ReflectionAttribute, and never before then. So, only when an attribute is actually read during reflection is it validated. Further, if you never actually instantiate it ... it is never actually validated (i.e., just looking for the presence of an attribute, not the details). https://3v4l.org/UqQKi — Rob
