Description:
------------
__get() and __set() are currently blocked from being implicitly called for a particular instance of an object when they are currently executing. However, this can cause code to behave differently if it is called from within __get()/__set() or if it is called without __get()/__set().

The following example uses good OOP methodology that tries to make use of __get() and __set(), but is hindered by it, instead.

The problem lies in the use of the in_get and in_set member variables in the zend_object strcut to provide a blanket block to calling __get or __set recursively (when called implicitly). A possible solution would be to only prevent code directly in the __get() and __set() method bodies from implicitly calling __get() or __set(), but allowing it in any called code.

Reproduce code:

Expected result:
----------------
correct behavior (without making use of __get/__set):<br>
before set : default<br>
after set  : propertyValue<br>
PropertyAccessClass Object
(
    [property:private] => propertyValue
    [defaultProperty:private] => default
    [changed:private] => 1
)
<br><br>

incorrect behavior (making use of __get/__set):<br>
before set : default<br>
after set  : propertyValue<br>
PropertyAccessClass Object
(
    [property:private] => propertyValue
    [defaultProperty:private] => default
    [changed:private] => 1
)

Actual result:
--------------
correct behavior (without making use of __get/__set):<br>
before set : default<br>
after set  : propertyValue<br>
PropertyAccessClass Object
(
    [property:private] => propertyValue
    [defaultProperty:private] => default
    [changed:private] => 1
)
<br><br>

incorrect behavior (making use of __get/__set):<br>
