so .. after a quick fiddle ..
It seem T::T automagically assumes that if you pass it a reference to
something then you probably didn;t want that, you prolly wanted the thingy
itself so it dereferences it for you.. it will only do this down one
level.
so by passing it a list of references it sees a list .. does a foreach
down them and then sees what it gets (in this case an array ref ) .. it
dereferences that and bingo you can now access the row of stuff.
however when the list jsut contains 1 item, it sees a reference to an
array ( whicj is the row) and then proceeds to do a foreach over the
elements of the row ..
by simply not passing it the thing in list format but passing the plain
reference (ie return $data instead of @{$data}) it always gets an arrayref
and works for both cases of 1 or n items in the array.
solved .. it just took me a while to twig what was going on.
