call_user_func(array($o,'f')); leads to fatal error, I think the same
internal mechanisms than $o->f() happens in call_user_func : the
closure gets ignored but like Stas said : this could lead to problems
with __get() and __call().

Anyway, for your use case to work, you should call $o->f->__invoke();
or call_user_func($o->f);
