Re: How to construct a struct that does not explicitly define a constructor

Thanks, I forgot about that syntax. Another question I have is 
if there's a way to do this inline:

```d
struct Test
{
    int n;
    float f;

    static Test opCall(int n, float f)
    {
        //return {n, f};            Error
        //return Test {n, f};       Error
        //return {n: n, f: f};      Error
        //return Test {n: n, f: f}; Error
    }
}

void main()
{
    auto test = Test(1, 2.0);
    assert(test.n == 1);
    assert(test.f == 2.0);
}
```

As you've been said, that does not work ATM but that is something 
that I expect to work from day one when D will have tuples

```d
struct Test
{
    int n;
    double f;
    static Test opCall(int n, float f)
    {
        return (0,0.1);
    }
}
```

because the tuple-expression `(0,0.1)` is explicitly convertible 
to `Test`, based on the concept of "structural typing".
