The AspectC++ parser does not yet instantiate templates per default. 
Because Security::Opaque (see above) is a template instance, the parser 
can not safely distinguish the declarations of the "operator>>=" 
functions, and thus fails to parse it. But you may try to rerun the ag++ 
call using the --real_instances command line option causing the 
AspectC++ parser to instantiate templates. Since template parsing is 
still in the testing phase, I can not promise that it works.

Hope this helps,
Matthias
