I am a newbie to D. From (C++,Java,others...) background.

In C++ I can say

void f1(int& pInt)
{
  pInt = 1;
}

which sets pInt(which is outside f1)
because although pInt (at compile time) is a Value
in reality it is passed by reference(address).

Now

void f2(int* pIntPtr)
{
  *pIntPtr = 1;
  ++pIntPtr;
  *pInt   = 2;
}
sets (the contents of) pInt to 1 (and the next immediate address to 2)

All this is of course standard C++.

How is this type of thing done in D
(changing objects by passing by reference etc)?
