Subject: Re: [PHP-DEV] Scalar Type Hint
From: will.fitch@gmail.com (Will Fitch)

That's the way to do it.  If you have an idea, such as this, write it =
up, and let's discuss.  If we don't, we end up talking about things =
(like scalar type hinting) that has been beaten to death on more than =
100 occasions (sarcasm, but not really...).  We can then have a =
reference to point to showing that the discussion is dead.  After 6 =
months, feel free to bring it up again.
