That is implemented, but notice the conditions that form a nested struct  
do not include "inside a class" or "inside a struct" (that "templated  
struct that has aliases to local functions as a template argument"  
condition is pretty specific, I'm talking about just putting it in any old  
struct).

This is decidedly different from a nested class:

http://www.digitalmars.com/d/2.0/class.html#nested

"A nested class is a class that is declared inside the scope of a function  
or another class. A nested class has access to the variables and other  
symbols of the classes and functions it is nested inside"

This is what the OP was desiring.
