I really like this alternative syntax:

<?php if($a): ?>
<h1>A is true.</h1>
<?php endif; ?>

I thought I was free from using curly brackets "{}", until I realized that I'd still have to define classes and functions in the old style:

<?php
class Old
{
    var $val;
    function Old($num=0)
    {
        print "<p>Created an object";
        if ($num > 0):
            print "this is mismatched syntax!";
        endif;
    }
}
?>

It seems a little jarring to have to switch back and forth between the "{}" and the alternative style in a class definition.  

It would be nice to be able to create an object with the alternative style syntax rather than with curly brackets.  It could look a little like this:

<?php
class Noo:
    var $val;
    function Noo():
        print "<p>Created a noo object";
    endfunction;
endclass;
?>

Wouldn't that be great?  My apologies if this is a redundant submission.  I searched for endclass and endfunction, but couldn't find them.
