How do you access variable declared in a class extension?

MyClass.h: ``` @interface MyClass : NSObject @end ``` MyClass.m: ``` // Define a private variable in a class extension @interface MyClass () { NSString *name; } @end ``` Then later on in lldb: ``` (lldb) po myClassInstance->name error: 'MyClass' does not have a member named 'name' error: 1 errors parsing expression ``` So how do you access that variable in the debugger? Using xcode 4.3.2 Thanks!
