i think the question is more along the lines of why cant static references
be embedded within double quoted strings like class instances (and
indirectly the issue i mentioned earlier this week, which affords a
workaround), as in

<?php
class Session { function blah() {} }
$s = new Session();
echo "Hi {$s->blah()} \n";
?>

whereas this doesnt work
<?php
class Session { static function blah() {} }
echo "Hi {Session::blah()} \n";
?>

the funny thing is, in php-5.2.4, you can get away w/ this
<?php
class Session { static function blah() {} }
$s = 'Session';
echo "Hi {$s::blah()} \n";
?>
