Hello internals, I saw the following on hacker-news the other day: https://news.ycombinator.com/item?id=42955176
In the article it talks about how many implementations do not emit a warning, and PHP is one of them (though the author didn't cover php explicitly). You can see this play out here: https://3v4l.org/8ih6O Since adding a warning here would be a BC break, does this need an RFC? I'd be happy to implement this and write the RFC if necessary. — Rob
