Unless I'm going mad (possible), default parameters are inserted and
passed by the compiler (at least on x86), so this will in fact be worse,
because that "0" will always be created and passed by the compiler
(because it might be needed for all it knows) whereas the empty classes
might eventually be optimised away with compiler improvements.

I see, I was afraid that something like that could happen, in principle (have never looked myself to the actual way defaults are compiled)

Thanks...
