So this may have been where I got off track.  I ran my existing pypp_api 
code and where it gets the decls from the parser the class that is 
returned is not a wrapper.  If I remember correctly it was just a 
namespace decl.  I will check this again tonight against the latest 
codebase and let you know if things are working correctly.

Okay, I guess that makes sense but the previous way of just importing 
the "decorating" aspects of call policies seemed to work pretty well.  
The user only thought of the call policies as decoration but behind the 
scenes he was giving you the exact classes that you needed to do the 
code generation.  This still seems like a valid separation and it seems 
like it would be the most simple design.

Thanks.
