Just move it to another function.

    namespace detail {
        std::string &string_cache()
        {
            static std::string str(arg, 'a');
            return str;
        }
    }
    template<typename T>
    T *Func(unsigned const arg)
    {
        std::string &str = detail::string_cache();
        /* other stuff here */
        return nullptr;
    }

Since this is already possible, please explain why this is too difficult /
cumbersome to use and what other advantages there would be.
