opDispatch/template get this

[Inquie via Digitalmars-d-learn]

I am using opDispatch to wrap function calls

Error: 'this' is only defined in non-static member functions, not 
opDispatch!"foo"

class X
{
    auto localfoo() { return 3; }
    template opDispatch(string name, Args...)
    {
        static if (name == `foo`) { alias opDispatch = () { 
return this.localfoo();
    };
}


which doesn't work because of this

I tried

template opDispatch(string name, this _this, Args...)
{
	static if (name == `foo`) { alias opDispatch = () { return 
_this.localfoo(); };
}

but that doesn't work either ;/

I call it like

auto y = x.foo();

but foo isn't found

class X
{
    auto localfoo() { return 3; }
    auto localfoo2(int x) { return x; }
    template opDispatch(string name, Args...)
    {
        static if (name == `foo`)
                {
                        alias opDispatch = () { return this.localfoo(); };
                }
                static if (name == `bar`)
                {
			alias opDispatch = () { return this.localfoo2(); }; // need to 
be able to pass Args properly here
                }
        }
}

void main()
{
        auto x = new X();
        auto z = x.localfoo();
        auto y = x.foo();
        auto q = x.bar();
}
