We still need to solve the delayed triggering of exceptions
thrown from C extensions or overloaded object handlers:
$obj->foo()->bar();
^
An exception thrown in foo() will not "detonate" until
the end of the statement (the semicolon).
What happens in this case is that $obj->foo() evalutates
to null and then engine will then E_ERROR out when trying
to call null->bar().
