No different from f1::x = 5. You can't look inside of the function scope. : > BTW are functions nested within member functions member functions? : Do we gain anything by making them member functions? I think it would be : superfluous; local function already has an access to "this" pointer through : its parent member function. Everything has access to the "this" pointer via &object. What are the rights? Nestesed class members may not access non-public members of the enclosing class. Derived class members may not access private members of the base class. : Though it may make sense for pointer : manipulation since the pointer to member function has a different type, so : maybe a new keyword can be added to specify member local function. No new keyword required. The local function is either a member and we use pointer to member or it is not and we use normal function pointer. All I see is a desire to use Pascal idioms in C++ without the details of how this will fit into the language. What are the gains and costs? John --- [ comp.std.c++ is moderated.
