That error suggests you're checking $t outside its scope. You define
it within the foreach loop - if you try to check it outside there
you'll see the error you mention.
You assign to $t on the line beginning "my $t". Try to see what's
inside it after you've assigned to it but within the same {} delimited
block.

Finding "good" CPAN modules involves a peculiar set of assessments. I
think the best way I've heard it described is as "a bit like
Goldilocks and the three bears" but I doubt that helps. Sorry.
Perhaps it's all about keeping trying them until you find the "just
right" modules for you.
