Call method of object variable

[Andrey via Digitalmars-d-learn]

Hi,
I have got:

struct Qaz
{
    wstring read() {return null;}
    wstring hear() {return "rrrr";} }

void main()
{
    // ...
    static if(some_condition) alias method = Qaz.hear;
    else alias method = Qaz.read;

    // ...
    Qaz qaz;

    qaz.method(); // ???
}

How to call alias "method" on object "qaz"?
