If func is a function (not a function pointer) with zero arguments, it works
correctly (I think). But if it is a function with >0 arguments, then it
complains that it cannot evaluate it.

Curiously, it generates the correct result, as evidenced by pragma(msg) below,
before giving the error.

--------------
double func0() { return 0; }
int func2(int a, int b) { return 2; }

void main()
{  
    static assert(typeof(func0).stringof=="(double())()"); // OK
    pragma(msg, typeof(func2).stringof);
    // bug.d(8): Error: expected 2 arguments, not 0
    // (int(int a, int b))()
    static assert(typeof(func2).stringof=="(int(int a, int b))()");
}
