Well, I believe the question of the nature of functions is not settled. C++ can fix some of the problems of C. And obviously, local functions as well as any other local objects should exist only in the scope where they are defined. > Or did you mean that returning a pointer to a local function would > need to be made a special case and disallowed?

Assignment of the local f-n ptr to the global var should be diagnosed as an error by compiler. The warning must be given when the pointer to the local f-n is returned by f-n. The same way as compiler gives warning if f-n returns ptr or ref to the local obj. No problems with passing a ptr to the local f-n to another f-n, as long as that f-n doesn't break any of the previous constraints, and call is originated in the scope where local f-n is defined.
