Description:
------------
PHP 4.* does not support calling object methods in the complex (curly) syntax.  The doc page at http://php.net/string does not have any version information for the complex syntax.

Reproduce code:
---------------
class foobar{
    function bar(){
        echo 'blah';
    }
}

$foo = new foobar();

echo <<<EOD
    <br /> this does NOT work on PHP 4.*: {$foo->bar()}
EOD;


Expected result:
----------------
PHP 5.1.6 prints 'blah' as expected.

Actual result:
--------------
PHP 4.4.0 and 4.4.4 print this error:

Parse error: syntax error, unexpected '(', expecting '}' in ...
