Well my problem is that sometimes I want to iterate through a numeric
range. If an article is ranked 4 stars then the designer can either
iterate through each ranking and display a star or he/she can simply
output "4 stars." (one customer likes the latter, another wants the
former). Likewise, I use Data::Page::Navigation for paginated data -
it's a really nice module, and if it displays 10 indexes at the bottom
of the page, say from 5 - 14, it would be nice if I could iterate
through them rather than doing it in Perl. It's not a religious
decision, it just gives the flexibility to the designers.

I hope this gives enough info. If I'm doing it wrong, I'm only too
pleased to be told if there's a better way. Michael Peters suggested
Javascript as one solution, although I'd prefer a solution in H::T if
possible. I have looked through the docs, and couldn't see anything
obvious, but was hoping that perhaps someone had solved this problem
before me via some kind of logic that I hadn't thought of.
