In article <3BF1567C.89167E12@san.rr.com>, Darren New says...
(talking about "Singleton")

Mmmm....(takes off shoes to facilitate the counting)...

I think I'd qualify, but I had never heard "Singleton" used that way until this
thread.

>A "singleton list" can never be expanded in math, since math is
>"functional" so to speak. That Ada isn't functional rules this out.

Ada *can* be used functionally, and the current strawman certianly provides for
that. I believe someone even tried to make that point earlier. It just isn't
exclusively functional.

>Is it possible to do the Singleton pattern in Ada? I guess a limited

If I created a package with only routines ("methods"), and a single global
object declared in the body that they all operate on, wouldn't that qualify?

>But certainly, if it causes confusion, a better name should be chosen.

I'd be more apt to blame the confusion on poor choice of naming by the OO
people, and move on. But then I'm not the one confused, either. :-)

I suppose we could just create a null list and make everyone "&" to that, just
to stop the bickering. :-)
