UFCS limit

[Antonio via Digitalmars-d-learn]

```d
auto doSomething(string text)
{
  return (string text2)
  {
    import std.stdio;
    writeln(text,",",text2);
  };
}
void main()
{
  doSomething("Hello")("X");
  "X".doSomething("Hello")();
}
```
Compiler error:

```
...
onlineapp.d(13):        expected 1 argument(s), not 2
```

I tried with some syntax change:

```d
void main()
{
  doSomething("Hello")("X");
  (doSomething("Hello"))("X"); // it works
  "X".(doSomething("Hello"))(); // fails!!!
}
```

```onlineapp.d(14): Error: identifier or `new` expected following 
`.`, not `(````

Is it there any way to apply UFCS on the returned method in the 
same expression?
