It's valid in Perl, and PHP's roots are in Perl :-)
The Objects page in the manual has an example of creating an object with just:
$cart = new Cart;
... no parens.
The definition of new (T_NEW) in Zend/zend_language_parser.y:425 (in PHP
4.4.0's source) looks to me like it accepts a variable - so "new $className" is
fine.
