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.

It shouldn't compile. -Walter
