Impossible to add template on operator() overload

I'm looking to add a template on an operator() overload, something like this:

struct Test {
    template<typename T>
    T operator()(const T x) {
        return x;
    }
    
};

[numthreads(32,1,1)]
void main() {
    Test t;
    t(5); // error
    t<uint>(5); // error
    t.operator()<uint>(5); // error
}

All syntax tests fail. Here is a link for testing: Link
Note that in C++ test(5) passes (the compiler infers the type) and t.operator()<uint>(5) passes as well.

Thank you in advance

Start with the linked Godbolt reproduction and the syntax tests mentioned in the issue, comparing the three operator() template forms with the corresponding C++ behavior. Done means the shown HLSL examples compile successfully, including both inferred and explicitly specified template calls.
