The definition of E_ERROR is "an error where the engine can't fully
recover", so if we can recover there should be no need for a vote ;-)

But I have doubts whether this works reliably in all cases where
functions are called. i.e. how will usort() behave? From a very quick
grep it seems that i.e. sapi/phpdbg doesn't check the return value of
zend_call_function, these things have to be reviewed too. Right now code
(should not but) could rely on the engine doing a bailout which will
shutdown the request on errors to call a function/method.
