Sure, you can collapse the inline functions to nil in NDEBUG

Something like 
dbgstream : public ostream {
#ifdef NDEBUG
  ostream &operator <<(int) { return *this; }
#else
  operator <<(int i) { cerr << i; return *this; }
#endif
}

You rely on the compiler to collapse all the unneeded ostreams, but
I think you can :)

Greetings, Stephan
