If I'm not mistaken it's a C++17 feature. You can also use this to 'pull'
specific methods out of specific bases (e.g. if there's a name
clash/ambiguity), not only for changing access scope.
E.g.
struct A
{
int foo(int);
};
struct B
{
double foo(double);
};
struct C : A, B
{
using A::foo;
using B::foo;
};
Which allows C to have `foo()` properly overloaded.
