Bug description:Operator `new' does not support expressions for class name
Description:
------------
Operator `new' accepts either class name as either symbol token or
variable
containing class name (T_STRING or
T_VARIABLE), but does not allow expressions returning class name.
Test script:
---------------
/* first form, works */
$handler = new SomeClass($constructorParam);
/* second form, works */
$handlerClass = handlerFor($something); /* returns name of some class to be
instantiated */
$handler = new $handlerClass($constructorParam);
/* third form -- does not work */
$handler = new (handlerFor($something))($constructorParam);
Expected result:
----------------
The third form ought to work just like the other two, so one doesn't need
to
create extra variable for single use.
Actual result:
--------------
PHP Parse error: syntax error, unexpected '(', expecting T_STRING or
T_VARIABLE
or '$'
