Hello Martin,

I'm sorry, but weaving *in* templates still does not work. The only 
template-related feature that should work, although experimental, is 
advice for calls to member functions of template instances, if the call 
itself is not located within the template. For example, if there is a 
call to Client<Something>::run() within your main() function, call 
advice should work.

Best regards,
