That is very good advice.

Before I submit a bug to Mantis that is typically exactly what I would do:
Either make a small simple program that replicates the error, or if
necessary for a horrible bug slice away everything from my program until
nothing but the bug is left.

But I'm not at that point yet.  And my best guess right now is that there
are hundreds of calls where nil is returned properly and I just happen to
have one specific case I discovered in which nil is not returned but a
VArraySet with count=0 is returned.

Eventually I'll take the time to investigate more.  For right now I'm
offering a "first alert".  I may end up being incorrect.

In the meantime I have turned off breakpoints when this occurs but continue
to log them in my error log.  I'll have to revisit all of this code again
soon anyway in January if and when you start tinkering with
FindValueAsArraySet to take a VArraySet argument (and hopefully use it as an
ordered set).

I'll let you know more when I do.
