I submit that it is a poor practice to write code that way.

Good question. It's a challenge. But it has to be done, or D will divide in half 
and both halves will fail.


We've had this discussion numerous times before - "throw the magic compiler 
switch" and D becomes an ARC system and everything is wonderful. It cannot work. 
ARC and GC are not equivalent.
