Chapter "Memory Management":

"D has built-in types that may be difficult to use without the 
GC: exceptions, strings, dynamic arrays, associative arrays, and 
delegate closures."

I would like to do something like this:

interface Timer
{
     void delegate pCallbackFunction(void);

     this();
     void Start(ushort milliseconds, pCallbackFunction);
     void Halt();
     void Restart();
}
