This compiles:

struct foo

    int x;

    void opCall(int a)
    {
       x = a;
       printf("%d\n", x);
    }
}

int main(char[][] args)
{
    foo* f = new foo(3);
    printf("%d\n", f.x);
    (*f)(5);

    return 0;
}

Output is:
0
5

Should this compile?  Or should have f.x been initialized to 3?

Thanks

Hmmmm... probably shouldn't have compiled as there is no constructor that  
matches 'this(int)', which is what should have been invoked by the 'new  
foo(3)' statement. Certainly the opCall function should not have been  
called at construction time.
