Perhaps this was meant as rhetoric, but I think you may be right.
This morning I was Googling "singleton replacement" and someone
on another forum said Factory would do the job.

Do you know if this is for a current version of D? The compiler
is choking on the import statements, complaining that it can't
read std/thread.d and std/c/time.d

Thanks, Andre. Exactly what I was hoping for.
Thanks for the replies, fellow programmers. (generic, unisex, PC,

If I could trouble someone for a complete working example so I

Hi guys,
I ran into another snag this morning while trying to implement a
singleton. I found all kinds of examples of singleton
definitions, but nothing about how to put them into practice.
Can someone show me a code example for how one would actually use
a singleton pattern in D? When I

Thanks, Johan. In a way, I was hoping it was some kind of

I found a mention that in the definition of a delegate, a
function parameter and its type could be replaced by an

myTestRig.addOnDestroy(delegate void(Widget w) { quitApp(); } );
became:
myTestRig.addOnDestroy(delegate void(_) { quitApp(); } );
