This is one of those moments when as an adjunct professor I always take time out to tell my students how the watch works before I tell them what time it is.

First off a quick review of what an array reference is: 

# make an array reference:
my $ref = \@rry;
#
# or an anoonymous array: 
my $ref2=[ "stuff", "things", "goodies"];
</ocde>
If I have a function returning an arrey reference:
<code>
my $rows=$sth->fetchall_arrayref;

[download]
Then to dereference it I would do the following: 
my @array=@{$sth->fetchall_arrayref};

[download]

But wait! If I am passing an array to HTML::Template's param method then I'm going to want to pass an anoymous array such as: 

$template->param(selscene => [ @array ] );

[download]

Hope my brain fried ramblings make sense and help...
