I was surprised to see that the following works on g++, clang,
Microsoft. It fails on the Intel compiler.

    auto Func(void)
    {
        return [](int const a){ return a * 3; };
    }

    typedef decltype(Func()) Lambda;

    class MyClass : public Lambda {

    };

    int main(void)
    {
        MyClass obj;
    }
