Why does:

int myLength(char[] test) {
  return test.length;
}
char[] test = "hello";
test.myLength();

work, and not:

class foo {
  char[] d;
  this(char[] t) { d = t; }
}
viod myPrint(foo test) {
  printf("%.*s", test.d);
}
foo test = new test("hello");
test.myPrint();

? Is it just predefined for all the basic types, just arrays, or what?

At the moment it only works for arrays. int[],char[],etc
I would like to see it work for basic types also. int,long,float,etc.
Perhaps even for struct/union/class, though it would need to detect collissions eg.

class A
{
  void foo(){}
}

void foo(A a) {}

A a = new A();
a.foo();  //which one, the member or the stand-alone function?
