Subject: Re: [PHP-DEV] Another tiny syntax patch
From: rasmus@lerdorf.com (Rasmus Lerdorf)

We have talked about this before, and the conclusion was that if we are
going to have an invalid PI, we might as well make it <?= since it is
just as invalid as <?php= and just as easy to parse.  Now you save 8 chars.
