Hi,

I have to correct my previous mail and call it a day. Long story short:

I need to implement a begin() and end() inside this struct method 
offering standard iterators over the elements of the containers. 
Unluckily they collide with the structs created by the macro which are 
also unfortunately named "begin" and "end". I am basically out of 
options now, so it must be outside the class, or?
