The other issue, of course, is how the NullPointerException gets thrown. To focus on this issue, we can simplify the snippet as follows:
Integer someInteger = null;
int num = someInteger; // t...
Non-type template parameters
...having the data members recursively mangled according to their values (for base classes, for example we can apply depth-first, left-to-right traversal). But it's definitely not going to work for arbitrary classes.
