Why this form of usage of undefined property should be considered as
feature?

This is actually a feature. Can't seem to find where it's documented
though so reclassifying.

Description:
------------
When using a combined operator like += or ++ on an undefined class
member, it does not produce "undefined property" notice as expected.
Tested with all errors enabled.

Reproduce code:
---------------
$a+=5;
$b=new stdClass;
$b->a+=5;


Expected result:
----------------
Notice: Undefined variable: a
Notice: Undefined property: stdClass::$a

Actual result:
--------------
Notice: Undefined variable: a


------------------------------------------------------------------------
