Sorry for this off-topic:
in C++ is possible to have default arguments to member functions
(i.e. int foo( int bar = 3 ) {...} ) .
Could I have, as default value, the value of a member variable ?
(i.e. something like:

struct Question {
   int zoo;
   Question() : zoo(3) {}       // this makes evrybody happy ;)
   int foo( int bar = Question::zoo );
}

)
Directly inlined the compiler says that the data structure is not
complete.
If I put the function body outside the class def the compiler excuses:

        sorry, not implemented: operand of OFFSET_REF not understood

Is there a smart move-around ?
My dumb solution is :

struct Question {
   int zoo;
   int foo( int bar = -1 ); // where -1 is an impossible value
}

int Question::foo( int bar = -1 )
{
        if (bar == -1) bar = zoo;
                ...
}


G++ FAQs says nothing about it.
My Stroustrup (C++ Programming Language) says nothing about it.
BTW:
'Annotated reference C++ Manual' by B.S. and Ellis worths the money ?
I don't want an introduction to C++ nor a bare reference manual
