So what's the fix here? Why does a using A::f declaration inside class
B not work?
There's no f(int) in scope, only int(foo).
Which... the compiler kindly tells us:
do_foo.cpp: In function 'int main()':
do_foo.cpp:18: error: no matching function for call to 'B::f(int&)'
do_foo.cpp:12: note: candidates are: virtual void B::f(foo)
make: *** [do_foo.o] Error 1
You could always switch to A's scope:
But the best solution is to read up on WHY C++ works this way so
you can understand the implications that thousands of great minds
have already pondered.
