Thanks for your answer! I was actually trying to avoid creating my own
subclass for each type of input field. I can almost do what I want if
I create HTML::Widget::Indexed that stores the value of index (1, 2, 3
etc), but I run into problems when I try to retrieve the value of a
particular element. If the element knew about its "parent" widget that
stores the value of the index, it would be easier, but it does not.
I can show up later on IRC to discuss this - let me know what time is
good for you.
