Description:
------------
When I run this code:

foreach (@$formErrors as &$formError) {

I get this:

parse error, unexpected '&', expecting T_STRING or T_VARIABLE or '$' 

Something about using both the @ and the & in the same foreach loop. It
works with either one alone, just not both.

Reproduce code:
---------------
use the foreach on a non-existant array with references, and the @
statement modifier.

Expected result:
----------------
Should skip the foreach loop.

Actual result:
--------------
Doesn't work.
