Nested Template Specialization

Question

Having a brain fart... Is it possible to make something like this work?

template struct Foo
{
    template struct Bar;
};

template         


        

Answer 1

As the previous posters explained, this is not possible. You can however move the nested template into a non-template base class:

struct FooBase
{
    template struct Bar;
}
template struct Foo : public FooBase
{
};

struct FooBase::Bar<1> // specializing Bar
{
};
