This fails to compile:

struct S
{
     property T func(T)()
    {
        return T.init;
    }
}

void main()
{
    S s;
    s.func!int;
    static assert(__traits(compiles, s.func!int));
}

and gives this error:

test.d(13): Error: static assert  (__traits(compiles,s.func!(int))) is false


If you change s.func!int to s.func!int() in the __traits statement, then it
compiles. But while the program itself can handle s.func!int, __traits can't.
It needs the parens. And as soon as properties are fixed so that they _can't_
be called with parens, then this will be that much more of a problem.
