Hrmm... I hadn't realized that this didn't return execution to the
main script. I'll have to investigate.

You could use a 'catch' statement. That at least looks cleaner...

Unique in what sense?

I think arrays would be much faster and a better mechanism to use.
Or, actually, you could just use the filesystem. IIRC, other systems
do that...

Sounds complex and a bit slow.
