Andreas is probably the best person to explain their view; oddly I see NULL as it's own type as well, because are there are times where it's useful to determine the difference between NULL and an Empty String; but when looking at examples like user values (e.g. GET/POST/COOKIE) being checked (e.g. `strlen()` or `preg_match()`), encoded (e.g. shown on a web page with `htmlspecialchars()`), or simply modified (e.g. `trim()`), I don't see why those possible NULL values should lead to a Fatal Type Error (unless you are talking about an environment that uses NULL as an invalid value, but I suspect that's quite rare). I see this RFC as a balance in that regard, because real life is > messy. I really hope it passes and good luck! > Thank you Robert, it's right the balance I'm trying to find. Craig
