I have objects with a few 'virtual' properties that are handled by the _ _get and _ _set magic functions. Twig doesn't check for this if i use something like {{ foo.bar }}.
According to the manual:

* check if foo is an array and bar a valid element;
* if not, and if foo is an object, check that bar is a valid property;
* if not, and if foo is an object, check that bar is a valid method;
* if not, and if foo is an object, check that getBar is a valid method;
* if not, return a null value. 

I would like to see "if not, and if foo is an object, check that _ _get is a valid method and bar is returned by it" to this list.
