Yeah, I'm a perl newbie and I'm using the constructs the llama tells me
to use :)

If by "just as well" you mean "syntax error," then yes :) It's one of
the first things I tried.

I'm pursuing the intermediate-step path right now:

my @PSARef = @{$VisitArray[$i]->PSearchStructArray};
for(my $k = 0; $k < scalar(@{$PSARef[$j]->ClickPathArray}); $k++) {

but for some reason it's returning abnormal lengths that are invariant
with different iterations of the innermost loop.
